CC   -!- FUNCTION: This is a prokaryotic monoheme cytochrome, unreactive with
CC       mitochondrial cytochrome C oxidase or reductase. It functions in
CC       nitrite and nitrate respiration in Pseudomonas, but it is also found in
CC       other bacteria.
CC   -!- PTM: Binds 1 heme c group covalently per subunit.
