Noncanonical Peloruside A Biosynthesis by an Uncultivated Verrucomicrobiota Symbiont
Angewandte Chemie, EarlyView.Noncanonical biochemistry of the peloruside PKS characterized in this work, comprising double bond generation by a noncanonical tridomain (blue), acetyl‐CoA recycling (orange), and proofreading systems (purple and yellow). The Z‐double bond is installed by TEB1 through O‐acetylation and acetate elimination. The acyl ligase PelB (AL, orange) selectively
