The structures of nitrite reductase from Paracoccus denitrificans GB17, (NiR-Pd) and Pseudomonas aeruginosa (NiR-Pa) have been described for the, oxidized and reduced state (Fulop, V., Moir, J. W. B., Ferguson, S. J., and Hajdu, J. (1995) Cell 81, 369-377; Nurizzo, D., Silvestrini, M. C., Mathieu, M., Cutruzzola, F., Bourgeois, D., Fulop, V., Hajdu, J., Brunori, M., Tegoni, M., and Cambillau, C. (1997) Structure 5, 1157-1171; Nurizzo, D., Cutruzzola, F., Arese, M., Bourgeois, D., Brunori, M., Cambillau, C. , and Tegoni, M. (1998) Biochemistry 37, 13987-13996). Major conformational, rearrangements are observed in the extreme states although they are more, substantial in NiR-Pd. The four structures differ significantly in the c, heme domains. Upon reduction, a His17/Met106 heme-ligand ... [[http://ispc.weizmann.ac.il/pmbin/getpm?10329702 (full description)]]
