The heme/Cu sulfite reductase bears a distal Cu metal coordinated to two cysteines. This enzyme catalyzes the reduction of sulfite to HS. Very little is known about the electronic structure and reactivity of this enzyme.

- - The study examines how thiol oxidation occurs with oxygen, using ferrous porphyrins as catalysts, by capturing and analyzing intermediates at low temperatures.
- - An initial Fe(III)-O compound is created, which then experiences proton-coupled electron transfer (PCET) to produce an Fe(III)-OOH species.
- - This process leads to the breaking of the O-O bond, resulting in the formation of an Fe(IV)=O compound and oxidizing the thiol into an RSOH group.
