Accepted name: oxaloacetate decarboxylase (Na+ extruding)
Reaction: oxaloacetate + 2 Na+[side 1] = pyruvate + CO2 + 2 Na+[side 2]
Other name(s): oxaloacetate β-decarboxylase (ambiguous); oxalacetic acid decarboxylase (ambiguous); oxalate β-decarboxylase (ambiguous); oxaloacetate carboxy-lyase (ambiguous)
Systematic name: oxaloacetate carboxy-lyase (pyruvate-forming; Na+-extruding)
Comments: The enzyme from the bacterium Klebsiella aerogenes is a biotinyl protein and also decarboxylates glutaconyl-CoA and methylmalonyl-CoA. The process is accompanied by the extrusion of two sodium ions from cells. Some animal enzymes require Mn2+. Differs from EC (oxaloacetate decarboxylase) for which there is no evidence for involvement in Na+ transport.
