A, B [auth C], D [auth B], E | PF12161 | HsdM N-terminal domain (HsdM_N) | HsdM N-terminal domain | This domain is found at the N-terminus of the methylase subunit of Type I DNA methyltransferases. 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 ... | Domain |
C [auth D], F [auth G] | PF01420 | Type I restriction modification DNA specificity domain (Methylase_S) | Type I restriction modification DNA specificity domain | This domain is also known as the target recognition domain (TRD). Restriction-modification (R-M) systems protect a bacterial cell against invasion of foreign DNA by endonucleolytic cleavage of DNA that lacks a site specific modification. The host ge ... | Domain |
