Rv0252: INVOLVED IN NITRATE ASSIMILATION(DENITRIFICATION) (AT THE SECOND STEP). THIS ENZYME IS AFAD FLAVOPROTEIN THAT ALSO CONTAINS A SIROHEME AND ONE2FE-2S IRON-SULFUR CENTER [CATALYTIC ACTIVITY: 3 NAD(P)H +nitrite = 3 NAD(P)+ + NH4OH + H2O.]
Rv0252, (MTV034.18), len: 853 aa. Probable nirB(alternate gene name: nasB), nitrite reductase [NAD(P)H]large subunit (EC 1.6.6.4), flavoprotein containingsiroheme and a 2FE-2S iron-sulfur centre. Highly similarto many others bacterial enzymes e.g. P08201|NIRB_ECOLINITRITE REDUCTASE (NAD(P)H) LARGE SUBUNIT from Escherichiacoli strain K12 (847 aa), FASTA scores: opt: 2775, E(): 0,(49.8% identity in 840 aa overlap); Q06458|NIRB_KLEPNNITRITE REDUCTASE (NAD(P)H) LARGE SUBUNIT (957 aa), FASTAscores: opt: 2902, E(): 0, (54.2% identity in 827 aaoverlap). Contains PS00365 Nitrite and sulfite reductasesiron-sulfur/siroheme-binding site. HOMODIMER WHICHASSOCIATES WITH NIRD|Rv0253. COFACTORS: FAD; Iron;Siroheme. TBparse score is 0.903.; nasB

Rv0253: INVOLVED IN NITRATE ASSIMILATION(DENITRIFICATION); REQUIRED FOR ACTIVITY OF THE REDUCTASE[CATALYTIC ACTIVITY: 3 NAD(P)H + nitrite = 3 NAD(P)+ +NH4OH + H2O.]
Rv0253, (MTV034.19), len: 118 aa. Probable nirD,nitrite reductase [NAD(P)H] small subunit (EC 1.6.6.4),similar to others e.g.P23675|NIRD_ECOLI|B3366|Z4727|ECS4217 from Escherichiacoli strains K12 and O157:H7 (108 aa), FASTA scores: opt:271, E():1.7e-12, (41.9% identity in 105 aa overlap).ASSOCIATES WITH NIRB|Rv0252. TBparse score is 0.913.
