  • Title: The primary structure of cytochrome P460 of Nitrosomonas europaea: presence of a c-heme binding motif.
    Author: Bergmann DJ, Hooper AB.
    Journal: FEBS Lett; 1994 Oct 24; 353(3):324-6. PubMed ID: 7957885.
    Abstract:
    Cytochrome P460 and hydroxyamine oxidoreductase of Nitrosomonas europaea both catalyze the oxidation of hydroxylamine and contain a 460 nm-absorbing chromophore. The gene (cyp) encoding cytochrome P460 was cloned and sequenced. The predicted amino acid sequence contains a single c-heme binding motif (CXXCH) near the carboxy-terminus. Cytochrome P460 shows little sequence homology to other c-cytochromes including hydroxyamine oxidoreductase. The presence of a signal peptide and a possible c-heme binding site suggest that the cytochrome P460 of N. europaea is periplasmic.
