The structures at 2.0 and 2.25 A resolution of native and recombinant, nitrite reductase from Alcaligenes faecalis show that they are identical, to each other and very similar to nitrite reductase from Achromobacter, cycloclastes. The crystallographic structure of a mutant, M150E, which, unlike the wild-type protein cannot be reduced by pseudoazurin, shows that, the glutamate replacement for methionine binds to a metal at the type I Cu, site via only one oxygen. Anomalous scattering data collected at, wavelengths of 1.040 and 1.377 A reveal that the metal at the type I site, is a Zn. No significant differences from the native structure other than, local perturbations at the type I site are seen. A local pseudo 2-fold, axis relates the two domains of different monomers which form the ... [[http://ispc.weizmann.ac.il/pmbin/getpm?7547950 (full description)]]
