The pentose phosphate pathway (PPP) is an important metabolic pathway for yielding reducing power in the form of NADPH and production of pentose sugar needed for nucleic acid synthesis. Transketolase, the key enzyme of non-oxidative arm of PPP, plays a

The interaction of transketolase ketosubstrates with the holoenzyme has been studied. On addition of ketosubstrates cleaving both irreversibly (hydroxypyruvate) and reversibly (xylulose 5-phosphate), identical changes in the CD spectrum at 300-360 nm are observed. The changes in this spectral region
