Sumpor oksigenaza/reduktaza (EC 1.13.11.55, SOR, sumporna oksigenaza, sumporna oksigenaza reduktaza) je enzim sa sistematskim imenom sumpor:kiseonik oksidoreduktaza (formira vodonik-sulfid- and sulfit).^[1]^[2]^[3]^[4] Ovaj enzim katalizuje sledeću hemijsku reakciju

4 sumpor + 4H₂O + O₂

\rightleftharpoons

2 vodonik sulfid + 2 bisulfit + 2 H⁺

Ovaj enzim je prisutan u termofilnim mikroorganizmima. On sadrži u svakoj podjedinici jedan atom gvožđa koje nije vezano za hem. Elementrni sumpor je elektronski donor i jedan od akceptora. Kiseonik takođe može da bude akceptor.
