Figure 5. Sulfur metabolism in mitochondria.
Flow of sulfur metabolites in cells and mitochondria is shown with
responsible enzymes for each step. Enzymes involved in the supersulfide
production and sulfur oxidation pathway are shown in blue and green,
respectively. I, II, III and IV indicate complexes in electron transport
chain. Q and QH2 indicate ubiquinone and ubiquinol,
respectively.
