CC -!- FUNCTION: Catalyzes the formation of a hydroxyacyl-CoA by addition of
CC water on enoyl-CoA. Also exhibits 3-hydroxyacyl-CoA epimerase and 3-
CC hydroxyacyl-CoA dehydrogenase activities. Strongly involved in the
CC anaerobic degradation of long and medium-chain fatty acids in the
CC presence of nitrate and weakly involved in the aerobic degradation of
CC long-chain fatty acids. {ECO:0000269|PubMed:12270828,
CC ECO:0000269|PubMed:12535077}.
CC -!- CATALYTIC ACTIVITY:

CC ChEBI:CHEBI:137480; EC=4.2.1.17;
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a (3S)-3-hydroxyacyl-CoA + NAD(+) = a 3-oxoacyl-CoA + H(+) +
CC NADH; Xref=Rhea:RHEA:22432, ChEBI:CHEBI:15378, ChEBI:CHEBI:57318,

CC -!- CATALYTIC ACTIVITY:
CC Reaction=(3S)-3-hydroxybutanoyl-CoA = (3R)-3-hydroxybutanoyl-CoA;
CC Xref=Rhea:RHEA:21760, ChEBI:CHEBI:57315, ChEBI:CHEBI:57316;
CC EC=5.1.2.3;
CC -!- PATHWAY: Lipid metabolism; fatty acid beta-oxidation.
CC -!- SUBUNIT: Heterotetramer of two alpha chains (FadJ) and two beta chains
CC (FadI). {ECO:0000250}.
CC -!- INTERACTION:
CC P77399; P77293: yfdH; NbExp=2; IntAct=EBI-545361, EBI-545379;
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC -!- INDUCTION: Unlike the aerobic pathway, the anaerobic pathway is not
CC strongly repressed by FadR regulatory protein.
CC -!- SIMILARITY: In the N-terminal section; belongs to the enoyl-CoA
CC hydratase/isomerase family. {ECO:0000305}.
CC -!- SIMILARITY: In the central section; belongs to the 3-hydroxyacyl-CoA
CC dehydrogenase family. {ECO:0000305}.
