Protein

Quinol oxidase subunit 2

Gene

qoxA

Organism
Bacillus subtilis (strain 168)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Catalyzes quinol oxidation with the concomitant reduction of oxygen to water. Major component for energy conversion during vegetative growth. Subunit II transfers the electrons from a quinol to the binuclear center of the catalytic subunit I (By similarity).By similarity

Catalytic activityi

Ubiquinol-8 + O2 = Ubiquinone-8 + H2O.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into Uniref entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
