CONFORMATIONAL CHANGES OCCURRING UPON NO BINDING IN NITRITE REDUCTASE FROM PSEUDOMONAS AERUGINOSA
OverviewOverview
Nitrite reductase (NiR) from Pseudomonas aeruginosa (EC 1.9.3.2) (NiR-Pa), is a soluble enzyme catalyzing the reduction of nitrite (NO2-) to nitric, oxide (NO). The enzyme is a 120 kDa homodimer, in which each monomer, carries one c and one d1 heme. The oxidized and reduced forms of NiR from, Paracoccus denitrificans GB17 (previously called Thiosphaera pantotropha), (NiR-Pd) have been described [Fulop, V., et al. (1995) Cell 81, 369-377;, Williams, P. A., et al. (1997) Nature 389, 406-412], and we recently, reported on the structure of oxidized NiR-Pa at 2.15 A [Nurizzo, D., et, al. (1997) Structure 5, 1157-1171]. Although the domains carrying the d1, heme are almost identical in both NiR-Pa and NiR-Pd oxidized and reduced, structures, the c heme domains show a different pattern of c ... [(full description)]
