Reaction: oxaloacetate = pyruvate + CO2
Other name(s): oxaloacetate β-decarboxylase; oxalacetic acid decarboxylase; oxalate β-decarboxylase; oxaloacetate carboxy-lyase
Systematic name: oxaloacetate carboxy-lyase (pyruvate-forming)
Comments: Requires a divalent metal cation. The enzymes from the fish Gadus morhua (Atlantic code) and the bacterium Micrococcus luteus prefer Mn2+, while those from the bacteria Pseudomonas putida and Pseudomonas aeruginosa prefer Mg2+. Unlike EC 7.2.4.2 [oxaloacetate decarboxylase (Na+ extruding)], there is no evidence of the enzyme's involvement in Na+ transport.
