CC   -!- FUNCTION: Involved in the final steps of cholesterol and steroid
CC       degradation. Opens the last steroid ring of cholesterol by catalyzing
CC       the hydrolysis of (3E)-2-(2-carboxylatoethyl)-3-methyl-6-oxocyclohex-1-
CC       ene-1-carboxyl-CoA (COCHEA-CoA) to 6-methyl-3,7-dioxodecanedioyl-CoA
CC       (MeDODA-CoA). {ECO:0000250|UniProtKB:P9WPV9}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(3E)-2-(2-carboxylatoethyl)-3-methyl-6-oxocyclohex-1-ene-1-
CC         carboxyl-CoA + H2O = 6-methyl-3,7-dioxodecanedioyl-CoA;
CC         Xref=Rhea:RHEA:66364, ChEBI:CHEBI:15377, ChEBI:CHEBI:167101,
CC         ChEBI:CHEBI:167102; Evidence={ECO:0000250|UniProtKB:P9WPV9};
CC       PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:66365;
CC         Evidence={ECO:0000250|UniProtKB:P9WPV9};
CC   -!- PATHWAY: Steroid metabolism; cholesterol degradation.
CC       {ECO:0000250|UniProtKB:P9WPV9}.
CC   -!- SUBUNIT: Heterotetramer composed of 2 IpdA subunits and 2 IpdB
CC       subunits. {ECO:0000250|UniProtKB:P9WPV9}.
CC   -!- SIMILARITY: Belongs to the 3-oxoacid CoA-transferase subunit B family.
CC       {ECO:0000305}.
