WebSep 5, 2012 · Acyl carrier protein (ACP) domains shuttle acyl intermediates among the catalytic domains of multidomain type I fatty acid synthase and polyketide synthase (PKS) systems. It is believed that the unique function of ACPs is associated with their dynamic property, but it remains to be fully elucidated what type of protein dynamics is critical for …
WebThe underlying mechanisms for ACP-based interactions that are crucial to the core functions of polyketide biosynthetic enzymes are poorly understood. Therefore, further efforts are necessary to increase understanding of the polyketide biosynthetic machinery at the structural and biochemical levels. WebThe polyketide synthase product 8-deoxy-16-descarboxyl-16-methyl-amphoteronolide B was identified for the first time. In addition, the ketoreductase 10 domain of the polyketide synthase was specifically inactivated by targeted gene replacement. The resulting mutants produced truncated polyketide intermediates as linear polyenyl-pyrones.
