Cbb3-type cytochrome c oxidase subunit FixP

Gene

fixP

Organism
Bradyrhizobium diazoefficiens (strain JCM 10833 / IAM 13628 / NBRC 14792 / USDA 110)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

C-type cytochrome. Part of the cbb3-type cytochrome c oxidase complex. FixP subunit is required for transferring electrons from donor cytochrome c via its heme groups to FixO subunit. From there, electrons are shuttled to the catalytic binuclear center of FixN subunit where oxygen reduction takes place. The complex also functions as a proton pump.By similarity6 Publications

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 one 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.
