X-RAY STRUCTURE OF NI, CA CONCANAVALIN A AT ULTRA-HIGH RESOLUTION (0.94A)
Overview
The protonation states of aspartic acids and glutamic acids as well as, histidine are investigated in four X-ray cases: Ni,Ca concanavalin A at, 0.94 A, a thrombin-hirugen binary complex at 1.26 A resolution and two, thrombin-hirugen-inhibitor ternary complexes at 1.32 and 1.39 A, resolution. The truncation of the Ni,Ca concanavalin A data at various, test resolutions between 0.94 and 1.50 A provided a test comparator for, the ;unknown' thrombin-hirugen carboxylate bond lengths. The protonation, states of aspartic acids and glutamic acids can be determined (on the, basis of convincing evidence) even to the modest resolution of 1.20 A as, exemplified by our X-ray crystal structure refinements of Ni and Mn, concanavalin A and also as indicated in the 1.26 A structure of thrombin, both of ...
