A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC 2.3.1.239

Accepted Name
10-deoxymethynolide syntase.
Alternative Name(s)
(2S)-methylmalonyl-CoA:malonyl-CoA malonyltransferase (10-deoxymethynolide forming).
Reaction catalysed
Malonyl-CoA + 5 (2S)-methylmalonyl-CoA + 5 NADPH <=> 10-deoxymethynolide + 6 CoA + 6 CO(2) + 5 NADP(+) + 2 H(2)O
Comment(s)
  • The product, 10-deoxymethynolide, contains a 12-membered ring and is an intermediate in the biosynthesis of methymycin in the bacterium Streptomyces venezuelae.
  • The enzyme also produces narbonolide (see EC 2.3.1.240).
  • The enzyme has 29 active sites arranged in four polypeptides (pikAI - pikAIV) with a loading domain, six extension modules and a terminal thioesterase domain.
  • Each extension module contains a ketosynthase (KS), keto reductase (KR), an acyltransferase (AT) and an acyl-carrier protein (ACP).
  • Not all active sites are used in the biosynthesis.
