CUCUMBER STELLACYANIN, CU2+, PH 7.0
OverviewOverview
Stellacyanins are blue (type I) copper glycoproteins that differ from, other members of the cupredoxin family in their spectroscopic and electron, transfer properties. Until now, stellacyanins have eluded structure, determination. Here we report the three-dimensional crystal structure of, the 109 amino acid, non-glycosylated copper binding domain of recombinant, cucumber stellacyanin refined to 1.6 A resolution. The crystallographic, R-value for all 18,488 reflections (sigma > 0) between 50-1.6 A is 0.195., The overall fold is organized in two beta-sheets, both with four, beta-stands. Two alpha-helices are found in loop regions between, beta-strands. The beta-sheets form a beta-sandwich similar to those found, in other cupredoxins, but some features differ from proteins such as, ... [(full description)]
