Abstract
|
|
|
High-throughput protein X-ray crystallography offers a significant opportunity
to facilitate drug discovery. The most reliable approach is to determine the
three-dimensional structure of the protein-ligand complex by soaking the ligand
in apo crystals. However, protein apo crystals produced by conventional
crystallization in a solution are fatally damaged by osmotic shock during
soaking. To overcome this difficulty, we present a novel technique for growing
protein crystals in a high-concentration hydrogel that is completely gellified
and exhibits high strength. This technique allowed us essentially to increase
the mechanical stability of the crystals, preventing serious damage to the
crystals caused by osmotic shock. Thus, this method may accelerate
structure-based drug discoveries.
