For purity of reagents and enzyme preparations, xylulose-5-phosphate epimerase should be virtually free from ribose-5-phosphate isomerase. A contamination of less than 1% of the latter enzyme does not interfere because under the conditions of the method it only reacts very slowly with ribose-5-...
摘要: Ribose-5-phosphate isomerase and ribulose-5-phosphate kinase appear to show specificity for a particular ribulose 5-phosphate species. The effect of this specificity will be channeling of ribulose 5-phosphate from the isomerase to the kinase during photosynthesis....
Interconversion of a keto sugar (ribulose 5-phosphate or fructose-6-phosphate) and an aldo sugar (ribose 5-phosphate or glucose-6-phosphate) by an isomerase. 2 Inversion of the optical configuration of an optically active carbon atom, as in a conversion of ribulose 5-phosphate to xylulose 5...

The pentose phosphate pathway (PPP) confers protection against oxidative stress by supplying NADPH necessary for the regeneration of glutathione, which detoxifies H(2)O(2) into H(2)O and O(2). RPE functions in the PPP, catalyzing the reversible conversion of D-ribulose 5-phosphate to D-...
RuBPCase, D-ribulose-l,5-bisphosphate carboxylase/oxygenase (EC4.1.1.39) is the key enzyme of the reductive pentose phosphate cycle. Because of its biological significance, many structural studies on a number of plant and bacterial RuBPCases1 have been undertaken, including the enzyme isolated from...
