Protein

Cytochrome b-c1 complex subunit 2, mitochondrial

Gene

QCR2

Organism
Debaryomyces hansenii (strain ATCC 36239 / CBS 767 / JCM 1990 / NBRC 0083 / IGC 2968) (Yeast) (Torulaspora hansenii)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

This is a component of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex), which is part of the mitochondrial respiratory chain. The core protein 2 is required for the assembly of the complex (By similarity).By similarity

Caution

Does not seem to have a protease activity as it lack the zinc-binding site.Curated
