Abstract
1. 1. The reaction mechanism of glutathione reductase (NAD(P)H:oxidized glutathione oxidoreductase, EC 1.6.4.2) was studied. By varying the GSSG concentration, a series of parallel lines was obtained in the 1/vvs 1/[NADPH] plots. NADP+ is a competitive inhibitor towards NADPH and a noncompetitive one towards GSSG. Both GSSG and NADPH were
