== Function ==
[https://www.uniprot.org/uniprot/NIR_THIND NIR_THIND] Catalyzes the reduction of nitrite to ammonia, consuming six electrons in the process (PubMed:16500161, PubMed:22281743). Has very low activity toward hydroxylamine (PubMed:16500161). Has even lower activity toward sulfite (PubMed:16500161, PubMed:22281743). Sulfite reductase activity is maximal at neutral pH (PubMed:20944237).<ref>PMID:16500161</ref> <ref>PMID:20944237</ref> <ref>PMID:22281743</ref>
