Succinate dehydrogenase [ubiquinone] cytochrome b small subunit 1, mitochondrial

UniProtKB accession:  P92507

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Membrane-bound small subunit (CybS) of the mitochondrial electron transport chain complex II, which together with the membrane-bound large subunit (CybL), anchor the catalytic subunits to the inner mitochondria membrane (PubMed:10743611, PubMed:17933581, PubMed:2843227, PubMed:7822332, PubMed:8435436). During the parasitic larvae and adult stages, which occur in an anaerobic environment, complex II acts as a fumarate reductase by transferring electrons from rhodoquinol to fumarate (PubMed:10743611, PubMed:17933581, PubMed:2843227, PubMed:7822332, PubMed:8435436).
