CRYSTAL STRUCTURE OF THE DI-HAEM CYTOCHROME C PEROXIDASE FROM PSEUDOMONAS AERUGINOSA
Overview
BACKGROUND: Cytochrome c peroxidase from Pseudomonas aeruginosa (PsCCP), represents a new class of peroxidases which work without the need to, create a semi-stable free radical for catalysis. The enzyme is located in, the bacterial periplasm where its likely function is to provide protection, against toxic peroxides. The soluble 323-residue single polypeptide chain, contains two covalent c-type haems with very different properties: one of, them is a low-potential (-330 mV) centre where hydrogen peroxide is, reduced (the peroxidatic site); the other is a high-potential (+320 mV), centre which feeds electrons to the peroxidatic site from soluble, electron-shuttle proteins such as cytochrome c and azurin. RESULTS: The, crystal structure of the oxidized form of PsCCP has been determined to ... [(full description)]
