Abstract
1.
1. The formation of NADH-X from NADH in the presence of glyceraldehyde phosphate dehydrogenase (EC 1.2.1.12) at low pH is observed not only in the presence of pyrophosphate, citrate or phosphate, but also in the presence of arsenate.
2.
2. Stimulation of NADH-X formation by acetyl phosphate is dependent on the presence of enzyme-bound NAD+; however, added NAD+ is inhibitory.
3.
3. Inhibition of NADH-X formation by sulphydryl reagents is prevented by acetyl phosphate in the presence of pyrophosphate or citrate, but not in the presence of arsenate or phosphate.
4.
4. In the absence of other polyvalent anions, acetyl phosphate alone can stimulate the conversion of NADH into NADH-X at low pH.
5.
5. In the presence of acetyl phosphate, the relative rate of formation of NAD+ and NADH-X from NADH is dependent on the pH and the anions present.
