Accepted name: 2-oxoglutarate decarboxylase
Reaction: 2-oxoglutarate = succinate semialdehyde + CO2
Glossary: thiamine diphosphate = 3-[(4-amino-2-methylpyrimidin-5-yl)methyl]-5-(2-diphosphoethyl)-4-methyl-1,3-thiazolium
Other name(s): oxoglutarate decarboxylase; α-ketoglutarate decarboxylase; α-ketoglutaric decarboxylase; pre-2-oxoglutarate decarboxylase; 2-oxoglutarate carboxy-lyase
Systematic name: 2-oxoglutarate carboxy-lyase (succinate-semialdehyde-forming)
Comments: Requires thiamine diphosphate. Highly specific.
