UniProtKB - P25201 (MTA1_ACICA)
Protein
Modification methylase AccI
Gene
accIM
Organism
Acinetobacter calcoaceticus
Status
Functioni
This methylase recognizes the double-stranded sequence GTMKAC, causes specific methylation on A-5 on both strands, and protects the DNA from cleavage by the AccI endonuclease.
Catalytic activityi
- a 2'-deoxyadenosine in DNA + S-adenosyl-L-methionine = an N6-methyl-2'-deoxyadenosine in DNA + H+ + S-adenosyl-L-homocysteineEC:2.1.1.72
GO - Molecular functioni
- DNA binding Source: InterPro
- site-specific DNA-methyltransferase (adenine-specific) activity Source: UniProtKB-EC
GO - Biological processi
- DNA restriction-modification system Source: UniProtKB-KW
