Multiple copies of genes coding for electron transport proteins in the bacterium Nitrosomonas europaea

J Bacteriol. 1993 Apr;175(8):2445-7. doi: 10.1128/jb.175.8.2445-2447.1993.

Abstract

The genome of Nitrosomonas europaea contains at least three copies each of the genes coding for hydroxylamine oxidoreductase (HAO) and cytochrome c554. A copy of an HAO gene is always located within 2.7 kb of a copy of a cytochrome c554 gene. Cytochrome P-460, a protein that shares very unusual spectral features with HAO, was found to be encoded by a gene separate from the HAO genes.
