ccoN1

Gene
ccoN1
Protein
Cbb3-type cytochrome c oxidase subunit CcoN1
Organism
Pseudomonas stutzeri
Length
474 amino acids
Function
Cbb3-type cytochrome c oxidase is the component of the respiratory chain that catalyzes the reduction of oxygen to water. Subunits CcoN and CcoO form the functional core of the enzyme complex. Subunits CcoP and CcoQ may optionally bind to the core. CcoN is the catalytic subunit of the enzyme. Electrons originating in cytochrome c or a quinol are transferred to the bimetallic center formed by a high-spin heme and copper B. The complex also functions as a proton pump.
Similarity
Belongs to the heme-copper respiratory oxidase family.
