oxidoreductase activity, acting on a sulfur group of donors, NAD(P) as acceptor
|
GO_0016668 |
[Catalysis of an oxidation-reduction (redox) reaction in which a sulfur-containing group acts as a hydrogen or electron donor and reduces NAD or NADP.] |
|
sulfite reductase activity
|
GO_0016002 |
[Catalysis of the reaction: hydrogen sulfide + acceptor + 3 H2O = sulfite + reduced acceptor.] |
|
superoxide dismutase activity
|
GO_0004784 |

|
antioxidant activity
|
GO_0016209 |
[Inhibition of the reactions brought about by dioxygen (O2) or peroxides. Usually the antioxidant is effective because it can itself be more easily oxidized than the substance protected. The term is often applied to components that can trap free radicals, thereby breaking the chain reaction that normally leads to extensive biological damage.] |
|
oxidoreductase activity, acting on superoxide radicals as acceptor
|
GO_0016721 |
[Catalysis of an oxidation-reduction (redox) reaction in which a superoxide radical (O2- or O2.-) acts as a hydrogen or electron acceptor.] |
