  • Title: Crystallization of Bacillus subtilis tryptophanyl-tRNA synthetase.
    Author: Ala P, Xue H, Leung L, Xue YQ, Wong JT, Yang DS.
    Journal: J Mol Biol; 1993 Apr 05; 230(3):1089-90. PubMed ID: 8478922.
    Abstract:
    Tryptophanyl-tRNA synthetase from Bacillus subtilis was overexpressed in Escherichia coli and was purified using column chromatography on DEAE-Sephacel and hydroxyapatite columns. Single crystals of the synthetase were grown by vapor diffusion at 4 degrees C from pH 5.5 solutions of polyethylene glycol 8000 containing magnesium ATP and L-tryptophan. The crystals diffracted to about 4.0 A resolution at -150 degrees C and appeared to belong to the orthorhombic space group P2(1)2(1)2 with unit cell dimensions: a = 143.6 A, b = 111.6 A, c = 50.6 A with one dimer in the asymmetric unit.
