1 Here, we show that alpha-TOS inhibits succinate dehydrogenase (SDH) activity of complex II (CII) by interacting with the proximal and distal ubiquinone (UbQ)-binding site (Q(P) and Q(D), respectively). Ubiquinone aminoadipate-semialdehyde synthase Mus musculus
2 Here, we show that alpha-TOS inhibits succinate dehydrogenase (SDH) activity of complex II (CII) by interacting with the proximal and distal ubiquinone (UbQ)-binding site (Q(P) and Q(D), respectively). Ubiquinone aminoadipate-semialdehyde synthase Mus musculus
3 We propose that alpha-TOS displaces UbQ in CII causing electrons generated by SDH to recombine with molecular oxygen to yield ROS. Ubiquinone aminoadipate-semialdehyde synthase Mus musculus
