| + | [https://www.uniprot.org/uniprot/PIKA2_STRVZ PIKA2_STRVZ] Involved in the biosynthesis of 12- and 14-membered ring macrolactone antibiotics such as methymycin/neomethymycin and pikromycin/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.<ref>PMID:10421766</ref> <ref>PMID:21570406</ref> <ref>PMID:19027305</ref> | ||
