Cytochrome c oxidase cbb3-type, subunit I (IPR004677)

Short name: Cyt_c_oxidase_cbb3_su1

Overlapping homologous superfamilies

Family relationships


This family represents the largest subunit, I, of the ccb3-type cytochrome c oxidase EC:, with two protohaem's and copper. It shows strong homology to subunits of other types of cytochrome oxidases. Species with this type, all from the proteobacteria so far, include Neisseria meningitidis, Helicobacter pylori, Campylobacter jejuni, Rhodobacter sphaeroides, Rhizobium leguminosarum, amongst others.
