Elucidating hydroxylation and methylation steps tailoring piericidin A1 biosynthesis

Org Lett. 2014 Feb 7;16(3):736-9. doi: 10.1021/ol4034176. Epub 2014 Jan 10.

Abstract

The piericidin A1 (1) gene cluster was identified from the deep-sea derived Streptomyces sp. SCSIO 03032. Our in vivo and in vitro experiments verified PieE as a 4'-hydroxylase and PieB2 as a 4'-O-methyltransferase, allowing the elucidation of the post-PKS modification steps involved in 1 biosynthesis. In addition, the shunt metabolite piericidin E1 (7) was identified as a novel analogue featuring a C-2/C-3 epoxy ring.
