... mechanism based on the TrxL2/2CP redox cascade. Glucose-6-phosphate dehydrogenase (G6PDH) catalyzes the first step of the oxidative pentose phosphate pathway (OPPP). Biochemical studies, including redox state determination and measurement of enzyme activity, suggested that the TrxL2/2CP pathway is involved...

Although the molecular mechanisms underlying the redox regulation of several TRX-regulated enzymes have been investigated in detail, only partial information was available for plastidial G6PDH (glucose-6-phosphate dehydrogenase...
