Reaction: succinyl-CoA + 3-hydroxy-3-methylglutarate = succinate + (S)-3-hydroxy-3-methylglutaryl-CoA
Systematic name: succinyl-CoA:3-hydroxy-3-methylglutarate CoA-transferase
Other names: hydroxymethylglutarate coenzyme A-transferase; dicarboxyl-CoA:dicarboxylic acid coenzyme A transferase
Comments: Malonyl-CoA can also act as donor, but more slowly.
