Abstract

Summary: 2-Oxoglutarate decarboxylase from the lactic acid bacterium was purified by precipitation with PEG and ion-exchange chromatography. The strictly thiamin-pyrophosphate-dependent enzyme decarboxylated 2-oxoglutarate to succinic semialdehyde. Oxalacetate was metabolized to a lesser extent. The measured values for 2-oxoglutarate and thiamin pyrophosphate were 1 m and 0·03 m respectively. The enzyme had a molecular mass in the range 65-70 kDa, did not consist of subunits and showed significant similarities to the corresponding mitochondrial enzyme of .
