FunFam 136147: Methyltransferase domain protein

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Cypemycin N-terminal methyltransferase. [EC:]
2 S-adenosyl-L-methionine + N-terminal L-alanine-[cypemycin] = 2 S-adenosyl-L-homocysteine + N-terminal N,N-dimethyl-L-alanine- [cypemycin].
  • The enzyme, isolated from Streptomyces sp. OH-4156, can methylate a variety of oligopeptides, cyclic peptides such as nisin and haloduracin, and the epsilon-amino group of lysine.
  • Cypemycin is a peptide antibiotic, a member of the linaridins, a class of posttranslationally modified ribosomally synthesized peptides.
  • Formerly EC 2.1.1.n13.
