CC -!- FUNCTION: Part of a complex that catalyzes the reversible cleavage of
CC acetyl-CoA, allowing growth on acetate as sole source of carbon and
CC energy. The alpha-epsilon subcomponent functions as a carbon monoxide
CC dehydrogenase. The precise role of the epsilon subunit is unclear; it
CC may have a stabilizing role within the alpha(2)epsilon(2) component
CC and/or be involved in electron transfer to FAD during a potential FAD-
CC mediated CO oxidation. {ECO:0000255|HAMAP-Rule:MF_01134}.
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC pH dependence:
CC Optimum pH is 8-9.;
CC -!- PATHWAY: One-carbon metabolism; methanogenesis from acetate.
CC {ECO:0000255|HAMAP-Rule:MF_01134}.
CC -!- SUBUNIT: Heterotetramer of two alpha and two epsilon subunits. The ACDS
CC complex is made up of alpha, epsilon, beta, gamma and delta subunits
CC with a probable stoichiometry of (alpha(2)epsilon(2))(4)-beta(8)-
CC (gamma(1)delta(1))(8). {ECO:0000255|HAMAP-Rule:MF_01134}.
CC -!- SIMILARITY: Belongs to the CdhB family. {ECO:0000255|HAMAP-
CC Rule:MF_01134}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAM30381.1; Type=Erroneous initiation; Evidence={ECO:0000305};
