RT Syntrophomonas wolfei.";
RL PLoS ONE 8:E56905-E56905(2013).
CC -!- FUNCTION: Involved in syntrophic growth of S.wolfei with butyrate, as
CC part of the butyrate oxidation pathway. Probably catalyzes the beta-
CC keto thiolysis of acetoacetyl-CoA, leading to 2 acetyl-CoA molecules.
CC {ECO:0000305|PubMed:23468890}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2 acetyl-CoA = acetoacetyl-CoA + CoA; Xref=Rhea:RHEA:21036,
CC ChEBI:CHEBI:57286, ChEBI:CHEBI:57287, ChEBI:CHEBI:57288; EC=2.3.1.9;
CC Evidence={ECO:0000305|PubMed:23468890};
CC -!- PATHWAY: Lipid metabolism; butanoate metabolism.
CC {ECO:0000305|PubMed:23468890}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:23468890}.
CC -!- INDUCTION: Highly expressed during syntrophic growth with butyrate (at
CC protein level). Seems to be constitutively expressed.
CC {ECO:0000269|PubMed:23468890}.
CC -!- SIMILARITY: Belongs to the thiolase-like superfamily. Thiolase family.
CC {ECO:0000305}.
