GENERAL INFORMATION

COMMENTARY
LITERATURE
physiological function
-
tight correlation found between the extracellular endonuclease activity and the rate of thymidine uptake by actively growing cells suggesting that this nuclease is required for fulfilling the nucleotide pool of precursors of DNA biosynthesis during the transformation of hyphae into the aerial mycelium and conidia in stressful environmental conditions
physiological function
Q8LDW6
plant S1-like nucleases are the main class of enzymes involved in nucleic acid degradation during plant programmed cell death
physiological function
-
the S1 nuclease has an important function in DNA transcription, replication, recombination, and repair
evolution
Q8LDW6
the enzyme belongs to the plant S1-like nucleases class of enzymes. Different members of this family are characterized by a surprisingly large variety of catalytic properties, nucleolytic activities of all Arabidopsis thaliana S1-like paralogues, overview. In addition to Zn2+-dependent enzymes, this family also comprises nucleases activated by Ca2+ and Mn2+, which implies that the apparently well-known S1 nuclease active site in plant nucleases is able to cooperate with different activatory ions. Particular members of this class differ in their optimum pH value and substrate specificity. Plant representatives of this family evolve toward an increase in catalytic diversity. Phylogenetic analysis, overview. ENDO3 is the only nuclease, of all members of this family, that demonstrates activity characteristic of fungal S1-type nucleases and mung bean plant nuclease, i.e. it digests ssDNA under acidic pH and in the presence of Zn2+

at acidic pH the enzyme is 25times more active on single-stranded DNA than on double-stranded DNA and 3times more active on single-stranded DNA than on single-stranded RNA. At neutral pH the RNase activity exceeds the DNase activity. The enzyme nicks supercoiled RF-I plasmid DNA and rapidly cuts the phosphodiester bond across from the nick in the resultant relaxed RF-II plasmid DNA.

-
S1 nuclease hydrolyzes single-stranded DNA or RNA into 5'-phosphomononucleotide and 5'-phosphooligonucleotide, development of a sensitive and facile assay method using polycytosine oligonucleotide-templated silver nanoclusters, i.e. dC12-Ag NCs, as substrate, determination through the change in the fluorescence of the substrate. Polycytosine oligonucleotide can function as both the template for the stabilization of templated silver nanoclusters and the substrate of the S1 nuclease. Polycytosine oligonucleotide is degraded to mono- or oligonucleotide fragments

expression of ENDO3 is highly specific to flower development. It appears first in the shoot apex of an emerging inflorescence stem, remains high in young flowers and decreases gradually with the development of siliques. ENDO3 is preferentially expressed in the pistil and less abundantly in the stamen. The comparison of ENDO3 transcript levels in the whole pistil and separate ovules suggests that ENDO3 activity is mainly related to the ovule

analysis
-
development of a fluorescent method for simple detection of sequence-specific single-strand DNA in complex, contaminant-ridden samples directly without a DNA extraction and PCR step could simplify the detection of pathogens in the field and in the clinic. Upon clearing away redundant complementary ssDNA and possibly mismatched double strand DNA by using S1 nuclease, the fluorescent signal-to-noise ratio can be increased dramatically. It enables the method to be adaptable to three different types of DNA fluorescent dyes and the ability to detect target ssDNA in complex, multicomponent samples, like tissue homogenate from pork

straightforward detection of single-nucleotide polymorphisms in double-stranded DNA by using exonuclease III/nuclease S1/peptide nucleic acid system
molecular biology
-
a combination of S1 nuclease with two strands of pseudo-complementary peptide nucleic acid is useful for cleaving genomic DNA into desired fragments at targeted sites. The DNA analogue pseudo-complementary peptide nucleic acid, pcPNA, has a poly[N-aminoethylglycine] backbone and invades double-stranded DNA through Watson-Crick base-pairing. Through the invasion, single-stranded portions are formed at targeted sites in the genome and cut by the enzyme which hydrolyses only single-stranded DNA. The enzyme's mismatch-recognition activity was high enough to distinguish one base-pair difference in the invasion site. Enzyme cofactor Zn2+ suppresses the DNA invasion by pseudo-complementary peptide nucleic acid
