CRYSTALLOGRAPHIC STRUCTURE OF A BLUE COPPER NITRITE REDUCTASE FROM ALCALIGENES XYLOSOXIDANS
OverviewOverview
Copper-containing nitrite reductases (NiR's) have been conveniently, subdivided into blue and green NiR's which are thought to be redox, partners of azurins and pseudo-azurins, respectively. Crystal structures, of two green NiR's have recently been determined. Alcaligenes xylosoxidans, has been shown to have a blue-copper nitrite reductase (AxNiR) and two, azurins with 67% homology both of which donate electrons to it, effectively. The first crystal structure of a blue NiR (AxNiR) in its, oxidized and nitrite-bound forms, with particular emphasis to the Cu, sites, is presented. The Cu-Smet distance is the same as those in the, green NiR's. Thus, the length of this interaction is unlikely to be, responsible for differences in colour. Crystallographic data presented, here taken together ... [(full description)]
