Title: Yi-Qiang Cheng: Innovator in Polyketide Synthases

Introduction

Yi-Qiang Cheng is a prominent inventor based in Madison, WI (US). He has made significant contributions to the field of biochemistry, particularly in the study of polyketide synthases. With a total of 2 patents, his work has paved the way for advancements in genetic engineering and synthetic biology.

Latest Patents

Cheng's latest patents focus on discrete acyltransferases associated with type I polyketide synthases. His research includes the genetic and biochemical characterization of the leinamycin biosynthesis gene cluster from S-140. This study revealed two PKS genes, lnmI and lnmJ, which encode six PKS modules, none of which contains a cognate AT domain. The AT activity is provided in trans by a discrete protein, LnmG, which loads the malonyl coenzyme A extender unit onto the ACP domains of all six PKS modules. This finding provides a basis for methods of engineering modular polyketide synthases and polyketide synthase/nonribosomal peptide synthetases.
