Inhibition of Ribulose 1 , 5 - Diphosphate Carboxylase by 6 - Phosphogluconate 1 Received for publication

Abstract

6-Phosphogluconate is a much more effective inhibitor of the photosynthetic carboxylation enzyme, ribulose-1,5-diphosphate carboxylase, than other sugar phosphates and sugar acids of the reductive and oxidative pentose phosphate cycles. The inhibition appears to be noncompetitive with ribulose 1, 5-diphosphate. Since 6-phosphogluconate is unique to the… (More)
