Trapping and retaining intermediates in glycosyltransferases

Glycosyltransferases (GTs) attach sugar molecules to a broad range of acceptors, generating a remarkable amount of structural diversity in biological systems. GTs are classified as either “retaining” or “inverting” enzymes. Most retaining GTs typically use an SNi mechanism. In a recent article in th...

Sumario:Glycosyltransferases (GTs) attach sugar molecules to a broad range of acceptors, generating a remarkable amount of structural diversity in biological systems. GTs are classified as either “retaining” or “inverting” enzymes. Most retaining GTs typically use an SNi mechanism. In a recent article in the JBC, Doyle et al. demonstrate a covalent intermediate in the dual-module KpsC GT (GT107) supporting a double displacement mechanism.
