Acetyl-CoA decarbonylase/synthase complex subunit epsilon 1

UniProtKB accession:  Q46G05

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Part of a complex that catalyzes the reversible cleavage of acetyl-CoA, allowing growth on acetate as sole source of carbon and energy. The alpha-epsilon subcomponent functions as a carbon monoxide dehydrogenase (PubMed:6425262). The precise role of the epsilon subunit is unclear; it may have a stabilizing role within the alpha(2)epsilon(2) component and/or be involved in electron transfer to FAD during a potential FAD-mediated CO oxidation (PubMed:18621675).
