Soybean Lipoxygenase (LOX-3) at ambient temperatures at 2.0 A resolution

Overview

Flash-freezing is a technique that is commonly used nowadays to collect, diffraction data for X-ray structural analysis. It can affect both the, crystal and molecular structure and the molecule's surface, as well as the, internal cavities. X-ray structural data often serve as a template for the, protein receptor in docking calculations. Thus, the size and shape of the, binding site determines which small molecules could be found as potential, ligands in silico, especially during high-throughput rigid docking. Data, were analyzed for wild soybean lipoxygenase-3 (MW 97 kDa) at 293 and 93 K, and compared with the results from studies of its molecular complexes with, known inhibitors, structures published by others for a derivative of the, same enzyme (98 K) or a topologically close isozyme ...
