Protein Family Models

This family consists of cytochrome bd type terminal oxidases that catalyse quinol-dependent, Na+-independent oxygen uptake [2]. Members of this family are integral membrane proteins and contain a protohaem IX centre B558. One member of the family Swiss:O05192 is implicated in having an important role in micro-aerobic nitrogen fixation in the enteric bacterium Klebsiella pneumoniae [1]. The family forms an integral functional unit with subunit I, family Bac_Ubq_Cox, Pfam:PF01654. [1]. 9274021.
