Function
NCPPR_PYRHO Catalyzes the NAD(P)H-dependent reduction of polysulfide, CoA-polysulfides, and CoA persulfide, as well as the reduction of a range of other small persulfides, including TNB and glutathione persulfides. The likely in vivo substrates are di-, poly-, and persulfide derivatives of coenzyme A, although polysulfide itself is also efficiently reduced (PubMed:23530771). Shows coenzyme A disulfide reductase (CoADR) activity with both NADH and NADPH, with a preference for NADPH (PubMed:15720393). May also play a role in the reduction of elemental sulfur (PubMed:23530771).[1] [2]
