Abstract
The effects of phosphate, arsenate, arsenite, and sulfate on lettuce seed (Lactuca sativa L.) glucose-6-phosphate dehydrogenase were investigated. All four substances inhibited the enzyme and inhibition was substrate dependent. The reaction was specific for glucose-6-phosphate and NADP. No effect of red or far-red light could be observed on enzyme activity. All enzyme activity was confined to the supernatant fraction.Keywords
