appC

Gene
appC
Protein
Cytochrome bd-II ubiquinol oxidase subunit 1
Organism
Escherichia coli (strain K12)
Length
514 amino acids
Function
A terminal oxidase that catalyzes quinol-dependent, Na(+)-independent oxygen uptake. Prefers menadiol over other quinols although ubiquinol was not tested (PubMed:8626304). Generates a proton motive force using protons and electrons from opposite sides of the membrane to generate H(2)O, transferring 1 proton/electron.
Similarity
Belongs to the cytochrome ubiquinol oxidase subunit 1 family.

Gene

Protein
Oligopeptide transport system permease protein AppC
Organism
Bacillus subtilis (strain 168)
Length
303 amino acids
Function
This protein is a component of an oligopeptide permease, a binding protein-dependent transport system. This APP system can completely substitute for the OPP system in both sporulation and genetic competence, though, unlike OPP, is incapable of transporting tripeptides. Probably responsible for the translocation of the substrate across the membrane (By similarity).
Similarity
Belongs to the binding-protein-dependent transport system permease family. OppBC subfamily.
