Functions
  • metal ion binding
  • electron carrier activity
  • 4 iron, 4 sulfur cluster binding
  • iron-sulfur cluster binding
  • 2 iron, 2 sulfur cluster binding
  • 3 iron, 4 sulfur cluster binding
  • succinate dehydrogenase (ubiquinone) activity
Processes
  • tricarboxylic acid cycle
  • aerobic respiration
Components
  • plasma membrane
General FunctionSuccinate dehydrogenase (ubiquinone) activity
Specific FunctionTwo distinct, membrane-bound, FAD-containing enzymes are responsible for the catalysis of fumarate and succinate interconversion; the fumarate reductase is used in anaerobic growth, and the succinate dehydrogenase is used in aerobic growth.
