Glossary: thiamine diphosphate = 3-[(4-amino-2-methylpyrimidin-5-yl)methyl]-5-(2-diphosphoethyl)-4-methyl-1,3-thiazolium
2-sulfoacetaldehyde = 2-oxoethanesulfonate
Other name(s): sulfopyruvate carboxy-lyase
Systematic name: 3-sulfopyruvate carboxy-lyase (2-sulfoacetaldehyde-forming)
Comments: Requires thiamine diphosphate. Does not decarboxylate pyruvate or phosphonopyruvate. The enzyme appears to be oxygen-sensitive.
