| + | Acyltransferases are responsible for the selective incorporation of an appropriate acyl building block in the biosynthesis of polyketide natural products. Proper protein-protein interactions between acyltransferase and cognate carrier protein are critical for the functional transfer of acyl groups. However, structural information on acyltransferase-carrier protein interactions is limited because of transient interactions between them. Understanding how each acyltransferase recognizes its cognate carrier protein is important for engineering polyketide biosynthetic pathways to produce novel compounds for drug discovery. | ||
| + | The acyltransferase VinK specifically interacts with the carrier protein VinL for substrate transfer in the biosynthesis of macrolactam antibiotic vicenistatin. The crystal structure of the VinK-VinL covalent complex formed with 1,2-bismaleimidoethane cross-linker has been determined previously. This paper describes the structural determination of the VinK-VinL complex formed with a pantetheine cross-linking probe. The interface interactions between VinK and VinL is essentially the same between these two VinK-VinL complex structures, suggesting that interface interactions are not affected by the cross-linking strategy used. This structural observation expands our understanding of the structure-function relationships of acyltransferases. | ||
