Structural characterization of EasH (Aspergillus japonicus) – an oxidase involved in cycloclavine biosynthesis†
Abstract
Aj_EasH is a non-heme iron- and α-keto-glutarate-dependent oxidase that is responsible for an unusual cyclopropyl ring formation in the biosynthesis of the fungal ergot alkaloid cycloclavine. The three dimensional structure of Aj_EasH (2.2 Å resolution) reported here provides insight into the mechanism of this unusual and complex reaction.
