Phosphorolytic cleavage
WebGlycogen phosphorylase causes phosphoroclastic cleavage into glycogen, and produces glycogen-1-phosphate. However, a non-reducing terminal is removed when cleaving glucose from glycogen. Moreover, if glucose-1-phosphate produced from glycogen is changed into G6P by phosphoglucomutase, it can proceed directly to glycolysis. WebApr 1, 2024 · The enzymes both catalyze phosphorolytic cleavage of xylulose 5-phosphate or fructose 6-phosphate in the first reaction step, but possess different substrate specificity in the second reaction step, where phosphoketolase and transketolase utilize inorganic phosphate (P i) and D-ribose 5-phosphate, respectively, as the acceptor substrate ...
