Accepted name: succinyl-CoA—L-malate CoA-transferase
Reaction: (1) succinyl-CoA + (S)-malate = succinate + (S)-malyl-CoA
(2) succinyl-CoA + (S)-citramalate = succinate + (S)-citramalyl-CoA

Glossary: (S)-citramalate = (2S)-2-hydroxy-2-methylbutanedioate
(S)-malate = (2S)-2-hydroxybutanedioate
(S)-malyl-CoA = (3S)-3-carboxy-3-hydroxypropanoyl-CoA
Other name(s): SmtAB
Systematic name: succinyl-CoA:(S)-malate CoA-transferase
Comments: The enzyme, purified from the bacterium Chloroflexus aurantiacus, can also accept itaconate as acceptor, with lower efficiency. It is part of the 3-hydroxypropanoate cycle for carbon assimilation.
