Structural Basis of Cyclized C17 Precursor Recognition and Product Formation in Chlororaphen and Grimophan Biosynthesis
Terpene cyclases (TCs) typically transform acyclic oligoprenyl pyrophosphates through carbocationic cyclization cascades. However, recently discovered bacterial pathways generate compact, cyclized and stereochemically defined noncanonical intermediates through methyltransferases prior to TC catalysis, raising the que...
