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

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

Reduction of cells or extracts of Nitrosomonas europaea with dithionite leads to a peak in
absorption spectra at 460 nm. Most of this chromophore is bound to hydroxylamine oxidase …

Abstract Cytochrome c-554 (Cyt c-554) was purified from Nitrosomonas europaea. The N-
terminal and internal amino acid sequences were determined. A synthetic …

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 …

Two membrane-associated cytochromes, cytochrome c m-553 and cytochrome c m-552,
were derived from Nitrosomonas europaea. The major c-type cytochrome, cytochrome c m …

Hydroxylamine oxidoreductase (HAO) catalyzes the oxidation of hydroxylamine to nitrite in
Nitrosomonas europaea. The electrons released in the reaction are partitioned to …

Nitrosomonas europaea is an ammonia-oxidizing bacterium which contains multiple c-type
cytochromes. Few of these components have been assigned physiological roles, but on the …

When a total soluble extract of Nitrosomonas europaea was denatured with dodecyl
sulphate, subjected to dodecyl sulphate/polyacrylamide-gel electrophoresis and illuminated …

ABSTRACT P460 cytochromes catalyze the oxidation of hydroxylamine to nitrite. They have
been isolated from the ammonia-oxidizing bacterium Nitrosomonas europaea (RH Erickson …
