This family are the alternative oxidases found in many bacteria which oxidise ubiquinol and reduce oxygen as part of the electron transport chain. This family is the subunit I of the oxidase E. coli has two copies of the oxidase, bo and bd', both of which are represented here In some nitrogen fixing bacteria, e.g. Klebsiella pneumoniae this oxidase is responsible for removing oxygen in microaerobic conditions, making the oxidase required for nitrogen fixation. This subunit binds a single b-haem, through ligands at His186 and Met393 (using SW:P11026 numbering). In addition His19 is a ligand for the haem b found in subunit II
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 Swi ...
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.
