EC 2.3.1.239 Details
EC number
2.3.1.239
Accepted name
10-deoxymethynolide synthase
Reaction
malonyl-CoA + 5 (2S)-methylmalonyl-CoA + 5 NADPH + 5 H+ = 10-deoxymethynolide + 6 CoA + 6 CO2 + 5 NADP+ + 2 H2O
Other name(s)
pikromycin PKS
Systematic name
(2S)-methylmalonyl-CoA:malonyl-CoA malonyltransferase (10-deoxymethynolide-forming)
Comment
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, narbonolide synthase). 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.
