Type III restriction-modification enzyme EcoP15I Mod subunit

UniProtKB accession:  P12364

Grouped By:  Matching UniProtKB accession

UniProtKB description:  A beta subtype methylase that binds the system-specific DNA recognition site 5'-CAGCAG-3' and methylates A-5 (of only 1 strand as the other does not have an A residue). DNA restriction requires both the Res and Mod subunits (PubMed:11178902, PubMed:12654995). The A-5 nucleotide flips into the catalytic pocket of one Mod subunit for modification, while the other Mod subunit makes most of the DNA sequence-specific contacts (PubMed:26067164).
