| Comment(s) |
|---|
- Glutathione (GSH) plays a catalytic role in elemental sulfur
activation, but is not consumed during the enzymic reaction.
- GSH and elemental sulfur react non-enzymically to yield
S-sulfanylglutathione and it is only in this form that the sulfur can
be oxidized to yield sulfite.
- The sulfite can be further converted into sulfate, thiosulfate or
S-sulfoglutathione (GSSO(3)(-)) non-enzymically.
