Enzymatic Fixation of Carbon Dioxide in α-Ketoglutaric Acid

Abstract
Reversibility of the opiation of alpha-ketoglutaric acid to succinic acid and CO2 was demonstrated with a cell-free enzyme prepn. of Escherichia coli. Adenosine triphosphate enhances the reversibility. This explains the capacity of alpha-ketoglutaric acid to replace CO2.
