2.6.1.5 hanging drop vapour diffusion method using 23.6% (w/v) PEG 4000, 0.1 M HEPES, pH 8.0 671159 2.6.1.5 low resolution structure of the enzyme bound to pyridoxal 5'-phosphate 640125 2.6.1.5 spontaneous crystallization when enzyme concentration is about 10 mg protein per ml 640098 2.6.1.5 structure determined at 2.5 A resolution 640124 2.6.1.5 the crystal structures of the holoenzyme and of the enzyme in complex with the inhibitor 2-aminooxyacetate reveal structural similarity to the beta-phenylalanine aminotransferase from Mesorhizobium sp. strain LUK 721359 2.6.1.5 through macromolecular crystallography the mTAT crystal structure is determined at 2.9 Å resolution. The crystal structure reveal the interaction between the pyridoxal-5'-phosphate cofactor and the enzyme, as well as the formation of a disulphide bond 723682
