Protein: Thiosulfate sulfurtransferase GlpE (EC 2.8.1.1) (P0A6V5)
Organism: Escherichia coli (strain K12)
Function: Catalyzes, although with low efficiency, the sulfur transfer reaction from thiosulfate to cyanide. The relatively low affinity of GlpE for both thiosulfate and cyanide suggests that these compounds are not the physiological substrates. Thioredoxin 1 or related dithiol proteins could instead be the physiological sulfur-acceptor substrate. Possible association with the metabolism of glycerol-phosphate remains to be elucidated.
Subcellular location: Cytoplasm.
