Abstract: Succinate:quinone oxidoreductases (SQORs, EC 1.3.5.1) are enzymes that couple the two-electron oxidation of succinate to fumarate (reaction 1) to the two-electron reduction of quinone to quinol (reaction 2):
succinate → fumarate + 2H+ + 2e- (1)
quinone + 2H+ + 2e- → quinol (2)
• Bioblast editor: Gnaiger E
- The 2H+ in reaction 1,
- succinate → fumarate + 2H+ + 2e- (1)
- has an entirely different meaning as the H+ in NADH + H+ shown in Figure 1a. In this figure, fumarate + 2H+ shown besides NADH + H+ is ambiguous [1].
