Outline of Final Research Achievements |
Aspartate:alanine antiporter AspT and its orthologues are industrially important solute exporters in bacteria. We established expression and purification systems for AspT with high yield and purity. We screened thermo-stable conditions for AspT in the presence of several ligands including substrates and their analogs. We performed crystallization of AspT and obtained some crystals at several optimized conditions. We collected X-ray diffraction data of AspT with the resolution of 4-6 Å, and are trying to improve molecular packing of crystals of AspT for better resolution.
