The two multiheme c-type cytochromes NrfH and NrfA form a membrane-bound complex that
catalyzes menaquinol oxidation by nitrite during respiratory nitrite ammonification of …

The crystal structure of cytochrome c 5 from Azotobacter vinelandii has been solved and
refined to an R value of 0.29 at 2.5 Å resolution. The structure of the oxidized protein was …

Cytochrome c-552 from Nitrosomonas europaea is a 9.1-kDa monoheme protein that is a
member of the bacterial cytochrome c-551 family. The gene encoding for c-552 has been …

We have determined the structure of n-butylisocyanide-bound Rhodobacter capsulatus
cytochrome c′. This is the first example of a ligand-bound structure of a class Ha …

The heme of cytochrome P460 of Nitrosomonas europaea, which is covalently crosslinked to
two cysteines of the polypeptide as with all c‐type cytochromes, has an additional novel …

Oxidation of membrane‐bound quinol molecules is a central step in the respiratory electron
transport chains used by biological cells to generate ATP by oxidative phosphorylation. A …

Background: Cytochromes c 4 are dihaem cytochromes c found in a variety of bacteria. They
are assumed to take part in the electron-transport systems associated with both aerobic and …

The molecular structures of ferri-and ferrocytochrome c 551 from Pseudomonas aeruginosa
have been refined at a resolution of 1.6 Å, to an R factor of 19.5% for the oxidized molecule …

Cytochromes-P460 of Nitrosomonas europaea and Methylococcus capsulatus (Bath), and
the cytochrome c′ of M. capsulatus, believed to be involved in binding or transformation of …

Hydroxylamine oxidoreductase (HAO) is a 24-heme homotrimeric enzyme that catalyzes the
conversion of hydroxylamine to nitrite in nitrifying bacteria: a key reaction in the nitrogen …
