28S rDNA + H2O
?
-
R1Bm EN cleaves both strands of the 28S rDNA sequence at the target site, 5'-A(G/C)(A/T)!(A/G)T-3' is the consensus sequence, thus cleavage site

-
?
Lambda DNA
Double-stranded fragments between 7 and 24 bases with 5' and/or 3'-protruding single-stranded tails
-
-
-
?
pBR322 DNA + H2O
DNA fragments carrying phosphate groups at 5' ends and hydroxyl group at the 3' ends, respectively
-
-
-
-
?
double-stranded DNA
?
-
preferably binds to the dinucleotide 5'-CC-3' and nicks DNA between both cytosines

double-stranded DNA
?
Virus NYs-1
-
the enzyme recognizes the sequence 5'-CC-3' and cleaves 5' to the first C. It cleaves 5'-CIIIC-3' sequences but not 5'-IIICC-3' sequences. The enzyme creates breaks in dsDNA whenever two 5-CC-3' sequences on opposite strands are close enough for the two strands to separate. When the 5'-CC-3' sequence on opposite strands are further apart only a portion of the strands separate

-
catalyzes the endonucleolytic cleavage of both the double- as well as the single-strand DNA non-specifically
