[[http://www.uniprot.org/uniprot/CDR_PYRHO CDR_PYRHO]] Acts as a coenzyme A disulfide reductase. Specific for CoA disulfide. Shows a slow NAD(P)H oxidase activity in the presence of high concentrations of substrate-level FAD. This demonstrates that it is not likely to act as an NADH oxidase in vivo.  
[https://www.uniprot.org/uniprot/NCPPR_PYRHO 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).<ref>PMID:15720393</ref> <ref>PMID:23530771</ref>
