New insights into bacterial type II polyketide biosynthesis

Bacterial aromatic polyketides, exemplified by anthracyclines, angucyclines, tetracyclines, and pentangular polyphenols, are a large family of natural products with diverse structures and biological activities and are usually biosynthesized by type II polyketide synthases (PKSs). Since the starting point of biosynthesis and combinatorial biosynthesis in 1984-1985, there has been a continuous ef...

Polyketide mimetics yield structural and mechanistic insights into product template domain function in nonreducing polyketide synthases.

Product template (PT) domains from fungal nonreducing polyketide synthases (NR-PKSs) are responsible for controlling the aldol cyclizations of poly-β-ketone intermediates assembled during the catalytic cycle. Our ability to understand the high regioselective control that PT domains exert is hindered by the inaccessibility of intrinsically unstable poly-β-ketones for in vitro studies. We describ...

Polyketide biosynthesis beyond the type I, II and III polyketide synthase paradigms.

Recent literature on polyketide biosynthesis suggests that polyketide synthases have much greater diversity in both mechanism and structure than the current type I, II and III paradigms. These examples serve as an inspiration for searching novel polyketide synthases to give new insights into polyketide biosynthesis and to provide new opportunities for combinatorial biosynthesis.

Structural insights into WcbI, a novel polysaccharide-biosynthesis enzyme

Capsular polysaccharides (CPSs) are protective structures on the surfaces of many Gram-negative bacteria. The principal CPS of the human pathogen and Tier 1 select agent Burkholderia pseudomallei consists of a linear repeat of --3)--2-O-acetyl-6-deoxy-β-d-manno-heptopyranose-(1-. This CPS is critical to the virulence of this emerging pathogen and represents a key target for the development of n...

Structural insights into the evolution of the pantothenate-biosynthesis pathway.

Pantothenate is synthesized in bacteria, fungi and plants, and as vitamin B5 is a dietary requirement in animals. The three-dimensional structures of the four Escherichia coli enzymes involved in the production of pantothenate have been determined. We describe the use of comparative analyses of the sequences and structures to identify distant homologues of the four enzymes in an attempt to unde...
