Om14p is a mitochondrial receptor for ribosomes with a function in the cotranslational import of mitochondrial proteins [37], Rdl1p is a putative mitochondrial
thiosulfate sulfurtransferase [38], while Mcr1p is a mitochondrial NADH-cytochrome b5 reductase with a known function in cellular ROS homeostasis [39].
Dose and time-dependent effects of cyanide on
thiosulfate sulfurtransferase, 3-mercaptopyruvate sulfurtransferase, and cystathionine A.-lyase activities.

thiosulfate sulfurtransferase (rhodanese) predicts mortality in hemodialysis patients," Clinical Biochemistry, vol.
Besides, [H.sub.2]S can be first oxidized to thiosulfate by sulfide oxidase and then converted to S[O.sub.2] catalyzed by
thiosulfate sulfurtransferase or glutathione-dependent thiosulfate reductase (Figure 1) [6, 24, 25].
