X-RAY REFINEMENT OF D2O SOAKED CRYSTAL OF CONCANAVALIN A
Overview
The correct positions of the deuterium (D) atoms of many of the bound, waters in the protein concanavalin A are revealed by neutron Laue, diffraction. The approach includes cases where these water D atoms show, enough mobility to render them invisible even to ultra-high resolution, synchrotron-radiation X-ray crystallography. The positions of the bound, water H atoms calculated on the basis of chemical and energetic, considerations are often incorrect. The D-atom positions for the water, molecules in the Mn-, Ca- and sugar-binding sites of concanavalin A are, described in detail.
