CC -!- FUNCTION: Catalyzes the transfer of the CoA moiety from acetyl-CoA CC to (R)-2-hydroxyglutarate and related compounds like glutaconate. CC -!- CATALYTIC ACTIVITY: Acetyl-CoA + (E)-glutaconate = acetate + CC glutaconyl-1-CoA. CC -!- PATHWAY: Amino-acid degradation; L-glutamate degradation via CC hydroxyglutarate pathway; crotonoyl-CoA from L-glutamate: step CC 3/5. CC -!- SUBUNIT: Heterooctamer of four A and four B subunits. CC -!- SUBCELLULAR LOCATION: Cytoplasm. CC -!- SIMILARITY: Belongs to the 3-oxoacid CoA-transferase subunit B CC family.
