摘要
GATC sequences in Escherichia coli DNA are methylated at the adenine residue by DNA adenine methyltransferase (DamMT). These methylated residues and/or the level of DamMT can influence cellular functions such as gene transcription, DNA mismatch repair, initiation of chromosome replication and nucleoid structure. In certain bacteria, unlike E coli, DamMT is essential for viability perhaps owing to its role in chromosome replication. DamMT has also been implicated as a virulence factor in bacterial pathogenesis. The origin and phylogeny of DamMT, based on sequenced genomes, has been deduced.
