Tropinone synthesis via an atypical polyketide synthase and P450-mediated cyclization
Abstract
Tropinone is an intermediate in the biosynthesis of tropane alkaloids. Here, the authors discovered the enzymes AbPYKS and AbCYP82M3, a non-canonical polyketide synthase and a cytochrome P450, that work sequentially to form tropinone from N-methyl-Δ1-pyrrolinium cation.
