CYTOCHROME P460 FROM NITROSOMONAS EUROPAEA- PROBABLE NONPHYSIOLOGICAL OXIDIZED FORM
OverviewOverview
We have determined the 1.8 A X-ray crystal structure of a monoheme c-type, cytochrome, cytochrome P460, from Nitrosomonas europea. The chromophore, possesses unusual spectral properties analogous to those of the catalytic, heme P460 of hydroxylamine oxidoreductase (HAO), the only known heme in, biology to withdraw electrons from an iron-coordinated substrate. The, analysis reveals a homodimeric structure and elucidates a new c-type, cytochrome fold that is predominantly beta-sheet. In addition to the two, cysteine thioether links to the porphyrin typical of c-type hemes, there, is a third proteinaceous link involving a conserved lysine. The covalent, bond is between the lysine side-chain nitrogen and the 13'-meso carbon of, the heme, which, following cross-link formation, is ... [(full description)]
