Dam methylase -> Dam

The methylase encoded by the dam gene ([http://en.wikipedia.org/wiki/Dam_(methylase) Dam methylase]) transfers a methyl group from S-adenosylmethionine to the N6 position of the adenine residues in the sequence GATC. When methylation occurs in the recognition site of a particular group of restriction endonuclease including MboI, this protects the DNA from cleavage.

Usage and Biology

DAM methylase (DNA adenine methylase) adds a methyl group to the adenine of the sequence 5'-GATC-3'in newly synthesized DNA. Dam methylases are important for several biological functions:

  • [http://en.wikipedia.org/wiki/DNA_replication DNA replication]
  • [http://en.wikipedia.org/wiki/Mismatch_repair DNA mismatch repair]
  • Regulation of protein expression.

In the E.ncapsulator project, we are using Dam methylase to protect the DNA from being destroyed by restriction enzymes DpnII(BBa_K200009) and TaqI(https://parts.igem.org/wiki/index.php?title=Part:BBa_K200009 BBa_K200010 BBa_K200010).
