Phosphopentose isomerase
WebPhosphopentose isomerase is an enzyme which converts ribulose 5-phosphate (a ketose) … WebPhosphopentose isomerase: Rbl5P is isomerized to ribose 5-phosphate (R5P), an end product. Phosphopentose epimerase : Rbl5P is epimerized to form xylulose 5-phosphate (Xy5P). Transketolase (contains thiamine pyrophosphate) : A 2-carbon exchange between Xy5P (5C) and R5P (5C) produces G3P (3C) and sedoheptulose 7-phosphate (7C).

Webphosphopentose isomerase. Under many metabolic conditions the phosphogluconate pathway ends at this point. The net result is the production of NADPH for reductive synthesis and the production of D-ribose-5-phosphate for nucleotide synthesis. However, many cells need more NADPH than ribose-5-phosphate or they may not need ribose-5-phosphate at all. Web潘 俨，孟新涛，车凤斌，薛素琳，张 婷，赵世荣，廖 康 （1新疆农业大学林学与园艺学院，乌鲁木齐 830052；2新疆农业科学院农产品贮藏加工研究所，乌鲁木齐 830091）

WebPyruvate kinase is a tetrameric enzyme that can exist as an L (found mostly in liver) or M (found mostly in muscles) form. What is true when comparing the L and M forms of pyruvate kinase? The M form is less susceptible to regulation by phosphorylation ATP is a co-substrate of the enzyme phosphofructokinase (PFK/PFK-1). WebRibose-5-Phosphate Isomerase.

WebThe pentose phosphate shunt (also known as the hexose monophosphate shunt or the 6-phosphogluconate pathway) shares the intermediates glyceraldehyde-3-phosphate and fructose-6-phosphate with the glycolytic pathway. Both pathways occur in the cytosol and, therefore, have access to one another.
