| - | + | [https://www.uniprot.org/uniprot/PIKA4_STRVZ PIKA4_STRVZ] Involved in the biosynthesis of 12- and 14-membered ring macrolactone antibiotics such as methymycin and neomethymycin, and pikromycin and narbomycin, respectively. Component of the pikromycin PKS which catalyzes the biosynthesis of both precursors 10-deoxymethynolide (12-membered ring macrolactone) and narbonolide (14-membered ring macrolactone). Chain elongation through PikAI, PikAII and PikAIII followed by thioesterase catalyzed termination results in the production of 10-deoxymethynolide, while continued elongation through PikAIV, followed by thioesterase (TE) catalyzed cyclization results in the biosynthesis of the narbonolide. The thioesterase can use a series of diketide-N-acetylcysteamine (SNAC) thioesters, but has a strong preference for the 2-methyl-3-ketopentanoyl-SNAC over the stereoisomers of 2-methyl-3-hydroxyacyl-SNAC (PubMed:12379101, PubMed:12733905).<ref>PMID:10421766</ref> <ref>PMID:10676969</ref> <ref>PMID:12379101</ref> <ref>PMID:12733905</ref> <ref>PMID:16969372</ref> <ref>PMID:17719493</ref> <ref>PMID:19027305</ref> | |
