TRI-IODIDE DERIVATIVE OF HEN EGG-WHITE LYSOZYME
Overview
A series of experiments performed at Cu Kalpha wavelength on in-house, X-ray equipment are presented which investigate two possibilities for, enhancing the experimental phasing signal by means of (i) triiodide/iodide, soaks using KI/I(2) and (ii) combinations of counter-ions introduced using, the short cryosoak method. Triiodide-derivative crystal structures for, five test proteins have been refined and reveal that iodine can bind as, polyiodide and single iodide ions through hydrophobic and hydrogen-bonding, interactions both at the molecular surface and in intramolecular and, intermolecular cavities. In three cases, the structures could be, automatically determined with autoSHARP using in-house SAD and SIRAS data., The investigation of combinatorial counter-ion replacement using ...
