The great GATC: DNA methylation in E. coli.
In Escherichia coli the methylation of the adenine in the sequence 5'-GATC-3' is catalysed by the dam gene product, a DNA adenine methylase. We review the proposed roles for this methylation, and the sequence it modifies, in mismatch repair, DNA-protein interaction, gene expression, the initiation of chromosome replication, chromosome segregation, chromosome structure and the occurrence of mutational hotspots.
