CRYSTAL STRUCTURE OF VERSATILE PEROXIDASE
Overview
Versatile peroxidases (VP), a recently described family of ligninolytic, peroxidases, show a hybrid molecular architecture combining different, oxidation sites connected to the heme cofactor. High-resolution crystal, structures as well as homology models of VP isoenzymes from the fungus, Pleurotus eryngii revealed three possibilities for long-range electron, transfer for the oxidation of high redox potential aromatic compounds. The, possible pathways would start either at Trp164 or His232 of isoenzyme VPL, and at His82 or Trp170 of isoenzyme VPS1. These residues are exposed, and, less than 11 A apart from the heme. With the purpose of investigating, their functionality, two single mutations (W164S and H232F) and one double, mutation (W164S/P76H) were introduced in VPL that: (i) removed ... [(full description)]
