Abstract Cytochrome c554 (cyt c554), a tetra-heme cytochrome from Nitrosomonas
europaea, is an essential component in the biological nitrification pathway. In N. europaea …

Abstract Cytochrome c 554 (cyt c 554) is a tetra-heme cytochrome involved in the oxidation
of NH 3 by Nitrosomonas europaea. The X-ray crystal structures of both the oxidized and …

Cytochrome c m552 (cyt c m552) from the ammonia-oxidizing Nitrosomonas europaea is
encoded by the cycB gene, which is preceded in a gene cluster by three genes encoding …

We have determined the 1.8 Å X-ray crystal structure of a monoheme c-type cytochrome,
cytochrome P460, from Nitrosomonas europea. The chromophore possesses unusual …

The tetraheme cytochrome c554 (cyt c554) from Nitrosomonas europaea is an essential
electron transfer component in the biological oxidation of ammonia. The protein contains …

Cytochrome P460 and hydroxylamine oxidoreductase (HAO) of Nitrosomonas europaea
catalyze the oxidation of hydroxylamine. Cytochrome P460 contains an unidentified heme …

The tetraheme cytochrome c 554 (cyt c 554) from Nitrosomonas europaea is believed to
function as an electron-transfer protein from hydroxylamine oxidoreductase (HAO). We show …

Cytochrome P460 and hydroxyamine oxidoreductase of Nitrosomonas europaea both
catalyze the oxidation of hydroxylamine and contain a 460 nm-absorbing chromophore. The …

The 2.8 Å crystal structure of hydroxylamine oxidoreductase of a nitrifying chemoautotrophic
bacterium, Nitrosomonas europaea, is described. Twenty-four haems lie in the centre bottom …

Cytochrome c nitrite reductase catalyzes the 6-electron reduction of nitrite to ammonia. This
second part of the respiratory pathway of nitrate ammonification is a key step in the …
