ProductPROBABLE NITRITE REDUCTASE [NAD(P)H] LARGE SUBUNIT [FAD FLAVOPROTEIN] NIRB
CommentsMb0258, nirB, len: 853 aa. Equivalent to Rv0252,len: 853 aa, from Mycobacterium tuberculosis strain H37Rv,(100.0% identity in 853 aa overlap). Probable nirB (alternate gene name: nasB), nitrite reductase [NAD(P)H] large subunit (EC 1.6.6.4), flavoprotein containing siroheme and a 2FE-2S iron-sulfur centre. Highly similar to many others bacterial enzymes e.g. P08201|NIRB_ECOLI NITRITE REDUCTASE (NAD(P)H) LARGE SUBUNIT from Escherichia coli strain K12 (847 aa), FASTA scores: opt: 2775, E(): 0,(49.8% identity in 840 aa overlap); Q06458|NIRB_KLEPN NITRITE REDUCTASE (NAD(P)H) LARGE SUBUNIT (957 aa), FASTA scores: opt: 2902, E(): 0, (54.2% identity in 827 aa overlap). Contains PS00365 Nitrite and sulfite reductases iron-sulfur/siroheme-binding site. HOMODIMER WHICH ASSOCIATES WITH NIRD|Rv0253. COFACTORS: FAD; Iron; Siroheme.
