Amylopectin phosphorolysis, phosphorylase

Arsenate similarly replaces phosphate in various phosphorolysis reactions, so that sucrose phosphorylase catalyzes the hydrolysis of sucrose in its presence (23), potato phosphorylase can hydrolyze amylose and amylopectin (24), nucleoside phosphorylase can hydrolyze inosine... 

In conclusion, phosphorylase b can bind strongly to the amylopectin substrate even as the inactivated form, and the enzyme is activated promptly by the addition of AMP leading to phosphorolysis of a-1,4 hnkages of amylopectin. This is the first example of simultaneous detection of the binding and catalysis of phosphorylase b reactions in situ on the same device.
