ENZYME

ENZYME entry: EC 7.2.4.3

Accepted Name
(S)-methylmalonyl-CoA decarboxylase (sodium-transporting)
Alternative Name(s)
(S)-2-methyl-3-oxopropanoyl-CoA carboxy-lyase
(S)-methylmalonyl-CoA carboxy-lyase
methylmalonyl-coenzyme A decarboxylase
Reaction catalysed
(S)-methylmalonyl-CoA + H(+)(out) + Na(+)(in) <=> CO2 + Na(+)(out) + propanoyl-CoA
Comment(s)
  • This bacterial enzyme couples the decarboxylation of (S)- methylmalonyl-CoA to propanoyl-CoA to the vectorial transport of Na(+) across the cytoplasmic membrane, thereby creating a sodium ion motive force that is used for ATP synthesis.
  • It is a membrane-associated biotin protein and is strictly dependent on sodium ions for activity.
  • Formerly EC 4.1.1.41.
