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.
