Offloading Role of a Discrete Thioesterase in Type II Polyketide Biosynthesis
Type II polyketides are a group of secondary metabolites with various biological activities. In nature, biosynthesis of type II polyketides involves multiple enzymatic steps whereby key enzymes, including ketoacyl-synthase (KSα), chain length factor (KSβ)

C–N bond formation by a polyketide synthase
Assembly-line polyketide synthases (PKSs) are molecular factories that produce diverse metabolites with wide-ranging biological activities. PKSs usually work by constructing and modifying the polyketide backbone successively. Here, we present the cryo-EM

Chemistry of a Unique Polyketide-like Synthase [PDF]
Like many complex natural products, the intricate architecture of saxitoxin (STX) has hindered full exploration of this scaffold's utility as a tool for studying voltage-gated sodium ion channels and as a pharmaceutical agent. Established chemical strategies can provide access to the natural product; however, a chemoenzymatic route to saxitoxin that ...

Investigation of the post-polyketide synthase (PKS) modifications during spinosyn A biosynthesis in Saccharopolyspora spinosa [PDF]
textDiverse biological activities of polyketide natural products are often associated with specific structural motifs, biosynthetically introduced after construction of the polyketide core. Therefore, investigation of such "post-polykektide synthase
