-
Exonucleolytic cleavage (in the presence of ATP) in either 5'- to 3'- or 3'- to 5'-direction to yield 5'-phosphooligonucleotides
mechanism, The enzyme is an ATP-dependent DNA exonuclease and a helicase, its exonuclease activity is subject to regulation by an octameric nucleotide sequence called chi.
-
Exonucleolytic cleavage (in the presence of ATP) in either 5'- to 3'- or 3'- to 5'-direction to yield 5'-phosphooligonucleotides
The enzyme generates 3 single-stranded DNA ends used by RecA for homologous recombination. The exonuclease activity is altered when the enzyme encounters a Chi sequence, 5-GCTGGTGG-3, in double-stranded DNA, an event critical to generation of 3 single-stranded DNA. Chi recognition requires that Chi be flanked by DNA at either end. A specific site for Chi recognition exists on enzyme, which binds Chi with greater affinity than a non-Chi sequence and is probably adjacent to non-specific DNA binding sites.
-
Exonucleolytic cleavage (in the presence of ATP) in either 5'- to 3'- or 3'- to 5'-direction to yield 5'-phosphooligonucleotides
The enzyme is involved initiating DNA recombination. The nuclease properties of the enzyme are regulated upon recognition of a specific DNA sequence by the translocating enzyme. This sequence, called chi, corresponds to the octamer 5-GCTGGTGG-3.
-
Exonucleolytic cleavage (in the presence of ATP) in either 5'- to 3'- or 3'- to 5'-direction to yield 5'-phosphooligonucleotides
The enzyme is required for homologous recombination and DNA repair, the degradative and recombinational activities of enzyme, as well as its structure, are regulated by a specific DNA sequence called Chi. The recombination requires loading of RecA by RecBCD enzyme and that the RecD subunit inhibits this reaction.
-
Exonucleolytic cleavage (in the presence of ATP) in either 5'- to 3'- or 3'- to 5'-direction to yield 5'-phosphooligonucleotides
the enzyme complex is activated once unwinding progresses. Extension of the 5'-tail of the unwound duplex induces a large conformational change in the RecD subunit, that is transferred through the RecC subunit to activate the nuclease domain of the RecB subunit. The process involves a SH3 domain that binds to a region of the RecB subunit in a binding mode that is distinct from others observed previously in SH3 domains

RecBCD enzyme is a multifunctional heterotrimeric complex that possesses processive helicase and exonuclease activities. Upon encountering the DNA regulatory sequence, chi, the enzymatic properties of RecBCD enzyme are altered. Its helicase activity is reduced, the 3'-5' nuclease activity is attenuated, the 5'-3' nuclease activity is up-regulated, and it manifests an ability to load RecA protein onto single-stranded DNA. The net result of these changes is the production of a highly recombinogenic structure known as the presynaptic filament

the nuclease reactions of the RecBCD-DNA complexes are initiated by mixing with ATP. The reaction is processive. The reaction begins near the 3'-end of the [5'-32P]DNA substrates and the major cleavage sites are two to four phosphodiester bonds apart. DNA cleavage is tightly coordinated with movement of the enzyme along the DNA. The reaction time-courses at low concentrations of ATP (0.1 mM and 0.025 mM) have a significant lag before cleavage products appear. We propose that the lag represents ATP-dependent movement of the DNA from an initial binding site in the helicase domain of the RecB subunit to the nuclease active site in a separate domain of RecB

when the concentration of ATP is greater than that of Mg2+ ions, RecBCD unwinds the DNA and nicks the Chi-containing strand of DNA a few nucleotides to the 3' side of the core sequence, continued unwinding produces 3'-ended ssDNA for strand exchange by RecA. When the concentration of Mg2+ ions is greater than that of ATP, RecBCD makes, during unwinding, occasional endonucleolytic nicks up to Chi on the 3'-ended strand, releasing fragments hundreds of nucleotides long, continued unwinding and similar nicking of the complementary strand produces 3'-ended ssDNA for strand exchange. A second round of RecBCD action is required to produce the acid-soluble, short oligonucleotides typically assayed as nuclease activity with purified enzyme and in repair-deficient cells (e.g. recA mutants) after DNA damage

enzyme RecBCD's repair of DNA is controlled by Chi, overview
metabolism
the RecBCD/AddAB complexes are highly processive helicase/nuclease machines that digest DNA from the broken end until they encounter a crossover hotspot instigator (Chi) sequence. At this point their activities are modulated to produce a 3-tailed duplex onto which RecA is loaded
physiological function
-
type I DNA restriction/modification systems are oligomeric enzymes capable of switching between a methyltransferase function on hemimethylated host DNA and an endonuclease function on unmethylated foreign DNA. Reuse of the methyltransferase subunits is possible so that restriction proceeds until the restriction subunits are depleted. RecBCD exonuclease halts restriction and does not assist recycling, influence of RecBCD on the EcoKI type I restriction enzyme, overview
physiological function
-
after transposition of phage Mu into the Escherichia coli chromosome, the flanking DNA is degraded, and the 5-bp gaps left in the target are repaired to generate a simple Mu insertion. The first event in repair is removal of the flanking DNA by RecBCD exonuclease, whose entry past the N-protein block is licensed by the transpososome. When RecBCD is allowed entry into the flanking DNA, it degrades this DNA until it arrives at the transpososome, which presents a barrier for further RecBCD movement. RecBCD action is required for stimulating endonucleolytic cleavage within the transpososome-protected DNA, leaving 4-nt flanks outside both Mu ends
physiological function
RecBCD (exonuclease V) plays a critical role in recombinational DNA repair. Escherichia coli RecBCD is involved in recombinational repair of double-strand breaks that are caused by defective DNA replication and other DNA damaging agents. Unrepaired DNA damage caused by cisplatin or UV light can lead to defective DNA replication and the production of double-strand breaks. Presence of adducts on the DNA double-helix can have major consequences for the efficient functioning of DNA repair enzymes. Escherichia coli RecBCD (exonuclease V) is involved in recombinational repair of double-strand breaks that are caused by defective DNA replication, DNA damaging agents and other factors. The holoenzyme possesses a bipolar helicase activity which helps unwind DNA from both 3'- and 5'-directions and is coupled with a potent exonuclease activity that is also capable of digesting DNA from both 3'- and 5'-ends
physiological function
RecBCD-type helicase-nuclease (RecBCD) catalyses the processing of double-stranded DNA breaks for repair by homologous recombination. The enzyme complex is a highly processive, duplex unwinding and degrading machine that requires tight regulation. The nuclease activity of the complex is activated once unwinding progresses
physiological function
repair of DNA double-strand breaks uses a highly conserved helicase-nuclease complex to unwind DNA from a broken end and cut it at specific DNA sequences called Chi. In Escherichia coli the RecBCD enzyme also loads the DNA strand exchange protein RecA onto the newly formed end, resulting in a recombination hotspot at Chi. Chi hotspots regulate multiple RecBCD activities by altering RecBCD's conformation, which is proposed to include the swinging of the RecB nuclease domain on the 19-amino-acid tether connecting the helicase and nuclease domains. Proper control of RecBCD by Chi requires that the tether be long enough and appropriately flexible. A model, in which the swing-time of the nuclease domain determines the position of Chi-dependent and Chi-independent cuts and Chi hotspot activity, is established. Generation of a molecular model for Chi-dependent nuclease swinging, and predictions of the nuclease-swing model, overview

the SH3 domain interacts with the ssDNA tail in a location different to that normally occupied by a peptide in canonical eukaryotic SH3 domains, thus retaining the potential to bind peptide at the same time as the ssDNA tail, interactions with the 5'-tail and the RecD subunit, overview. The N-terminal domain of RecD contacts the 2B domain of RecC and the conformational change in RecD has significant effects on the conformation of the RecC subunit. The RecB nuclease domain bridges a gap between the 1A and 2B domains of RecC and the conformational changes cause a significant shift in position of the RecB nuclease relative to these domains that reveals the mechanism for nuclease activation. Interaction between the 2B domain of RecD and the RecB subunit has a number of consequences, analysis of conformational changes that proceed from the initiation complex to nuclease activation
additional information
the tether (amino acids 881-899) of RecB is essential for Chi's stimulation of recombination. The tether can be lengthened somewhat without alteration of Chi's control, but a too-long tether significantly reduces Chi's control of RecBCD

-
RecB, RecC and RecD subunits, The nuclease active site on the RecB 30000 Da domain is the universal nuclease active site of enzyme that is responsible for single-stranded DNA degradation in both directions.
heterotrimer
-
RecB, RecC and RecD, The C-terminus of RecC: 35000 Da, is required for assembly of the RecD subunit into enzyme holoenzyme but not for recombination proficiency. The N-terminus of RecC: 95000 Da, contains functions essential for recombination and is also required for chi activity. RecD is essential for nuclease activity, regulation by the recombination hotspot Chi, and high affinity for DNA ends. RecC interacts with RecD to form a heterotrimer only in the presence of RecB.

Comparison: recB(D1080A)CD is recombinant-deficient, and sensitive to DNA damaging agents, and the purified enzyme failed to load RecA during DNA winding. recB(D1080A)C is recombinant-proficient and resistant to DNA damaging agents, and the mutant is active RecA loading assay.
additional information
the mutant RecB2109CD degrades the double-stranded DNA primarily in the 5 to 3 direction, producing processed double-stranded DNA with a 3-terminal overhang, the mutant is unable to coordinate the loading of RecA protein onto the single-stranded DNA produced, this inability can be responsible for recB2109 recombination defect observed in vivo
additional information
-
in mutants carrying either recB2109 or recD1903, which do not exhibit significant nuclease activities, the prophage progressively loses its capacity for both site-specific and general recombination
additional information

deletion of amino acids 881-899 (DELTA19) of RecB, the entire tether. The resulting mutant DELTA19 is recombination-deficient and has no detectable Chi activity. The mutant retained nuclease activity, demonstrating that it is not a null mutant. Additional construction of RecB mutants lacking one or another part of the tether. Inserting two foreign tethers, to make the tether 57 amino acids long, both reduce Chi activity and recombination proficiency to about the same level as that of RecBCD with the 38-amino-acid tethers. None of the mutants reported increases Chi hotspot activity. RecBCD enzymatic activities coincide with the genetic activities of the tether mutants
