CC   -!- FUNCTION: Catalyzes the final step of fatty acid oxidation in which
CC       acetyl-CoA is released and the CoA ester of a fatty acid two carbons
CC       shorter is formed. {ECO:0000255|HAMAP-Rule:MF_01620}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=an acyl-CoA + acetyl-CoA = a 3-oxoacyl-CoA + CoA;

CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01620};
CC   -!- PATHWAY: Lipid metabolism; fatty acid beta-oxidation.
CC       {ECO:0000255|HAMAP-Rule:MF_01620}.
CC   -!- SUBUNIT: Heterotetramer of two alpha chains (FadB) and two beta chains
CC       (FadA). {ECO:0000255|HAMAP-Rule:MF_01620}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01620}.
CC   -!- SIMILARITY: Belongs to the thiolase-like superfamily. Thiolase family.
CC       {ECO:0000255|HAMAP-Rule:MF_01620}.
