products description :
DNA adenine methylase (DAM) is an enzyme that methylates adenine residues in the 4-base pair DNA sequence, GATC. This methylation reaction has been shown to be crucial in a variety of cellular processes in bacteria. These include (i) the control of initiation of DNA replication (GATC occurs 11 times in the highly conserved bacterial origin of replication sequence); (ii) methyl-directed mismatch repair; (iii) control of transposition of certain transposable DNA elements; and (iv) control of gene expression. With regard to gene expression, the recent report by Heithoff et al. (Science; 284:967-970; 1999) showed that the deletion of the DAM gene rendered Salmonella typhimurium totally avirulent.

ncbi summary :
Dam is a base flipping enzyme. [More information is available at EcoGene: EG10204]. DNA adenine methyltransferase (Dam), which is responsible for methylation of nearly all GATC sequences in Escherichia coli , is encoded by the dam gene and occurs at about 130 molecules per rapidly growing cell . [More information is available at EcoCyc: EG10204].
uniprot summary :
Function: Methylates DNA within the sequence GATC and protects the DNA from cleavage by the restriction endonuclease MboI. Although it shares sequence specificity with a number of type II restriction endonucleases and methylases, it is thought to act in postreplication mismatch repair rather than as a part of a restriction modification system. May also play a role in DNA replication. Catalytic activity: S-adenosyl-L-methionine + DNA adenine = S-adenosyl-L-homocysteine + DNA 6-methylaminopurine. Sequence similarities: Belongs to the N(4)/N(6)-methyltransferase family.
