GN DAM. OS Bacteriophage T2. OC Viruses; dsDNA viruses, no RNA stage; Tailed phages; Myoviridae; OC T4-like phages. RN [1] RP SEQUENCE FROM N.A. RX MEDLINE; 89033901. RA MINER Z., HATTMAN S.; RT "Molecular cloning, sequencing, and mapping of the bacteriophage T2 RT dam gene."; RL J. Bacteriol. 170:5177-5184(1988). RN [2] RP MUTAGENESIS. RX MEDLINE; 90045940. RA MINER Z., SCHLAGMAN S.L., HATTMAN S.; RT "Single amino acid changes that alter the DNA sequence specificity of RT the DNA-[N6-adenine] methyltransferase (Dam) of bacteriophage T4."; RL Nucleic Acids Res. 17:8149-8157(1989). CC -!- FUNCTION: THIS METHYLASE RECOGNIZES THE DOUBLE-STRANDED SEQUENCE CC GATC, CAUSES SPECIFIC METHYLATION ON A-2 ON BOTH STRANDS. CC -!- CATALYTIC ACTIVITY: S-ADENOSYL-L-METHIONINE + DNA ADENINE = CC S-ADENOSYL-L-HOMOCYSTEINE + DNA 6-METHYLAMINOPURINE.
