Glycolysis arsenate effect

The idea that enzymes whose normal substrate is orthophosphate can use arsenate in its place, and that the esters of arsenate formed are rapidly hydrolyzed, was given by Braunstein (16) in 1931, to explain the effects of arsenate on glycolysis. This idea was formulated more precisely for glyceraldehyde-phosphate dehydrogenase in 1939. This enzyme, E—SH, normally oxidizes its aldehyde substrate with phosphate uptake to give an acyl phosphate, as follows ...
