FunFam 135253: Mycinamicin VI 2''-O-methyltransferase

There are 2 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
Demethylmacrocin O-methyltransferase. [EC: 2.1.1.102]
S-adenosyl-L-methionine + demethylmacrocin = S-adenosyl-L-homocysteine + macrocin.
  • The 2-hydroxyl group of a 6-deoxy-D-allose residue in demethylmacrocin acts as methyl acceptor.
  • Isolated from Streptomyces fradiae.
  • Also acts on demethyllactenocin giving lactenocin.
  • Involved in the biosynthesis of the macrolide antibiotic tylosin.
  • Not identical with EC 2.1.1.101.

Mycinamicin VI 2''-O-methyltransferase. [EC: 2.1.1.238]
S-adenosyl-L-methionine + mycinamicin VI = S-adenosyl-L-homocysteine + mycinamicin III.
  • The enzyme is involved in the biosynthesis of mycinamicin macrolide antibiotics.
  • Requires Mg(2+) for optimal activity.
