Spectroscopic identification of the haem ligands of cellobiose oxidase.
A spectroscopic study of the flavocytochrome b enzyme, cellobiose oxidase, employing optical, NMR, EPR and near infra-red MCD techniques, has identified the axial ligands of the b-type haem. These are a histidine and a methionine, and this ligation set is discussed in relation to the functional role of the haem group.
