>TIGR02374 nitri_red_nirB nitrite reductase [NAD(P)H], large subunit; InterPro: IPR012744 This entry describes NirB, the large subunit of nitrite reductase [NAD(P)H] (the assimilatory nitrite reductase), which associates with NirD, the small subunit (IPR012748 from INTERPRO). In a few bacteria such as Klebsiella pneumoniae and in fungi, the two regions are fused.; GO: 0008942 nitrite reductase [NAD(P)H] activity, 0050660 FAD binding, 0050661 NADP binding, 0042128 nitrate assimilation.
