This domain family is found in bacteria and archaea, and is typically between 123 and 138 amino acids in length. The family is found in association with Pfam:PF02384. Mutations in this region of EcoKI methyltransferase Swiss:P08957 abolish the normally strong preference of this system for methylating hemimethylated substrate [1]. The structure of this domain has been shown to be all alpha-helical.
