| - | Two thioesterases are commonly found in natural product biosynthetic clusters, a type I thioesterase (TEI) which is responsible for removing the final product from the biosynthetic complex, and a type II thioesterase (TEII) which is believed to perform housekeeping functions such as removing aberrant units from carrier domains. We present the crystal structure and the kinetic analysis of RifR, a TEII from the hybrid NRPS/PKS rifamycin biosynthetic cluster of Amycolatopsis mediterranei. Steady-state kinetics show RifR has a preference for the hydrolysis of acyl units from the phosphopantetheinyl arm (Ppant) of the acyl carrier domain, over the hydrolysis of acyl units from the Ppant of acyl-CoAs as well as a modest preference for the decarboxylated substrate mimics acetyl-CoA and propionyl-CoA over malonyl-CoA and methylmalonyl-CoA. Multiple RifR conformations and structural similarities to other thioesterases suggest that movement of a helical lid controls access of substrates to the active site of RifR. | ||
