    Journal: Acta Crystallogr D Biol Crystallogr; 2001 Aug; 57(Pt 8):1177-9. PubMed ID: 11468411.
    Abstract:
    The archaebacterial-type aspartyl-tRNA synthetase (AspRS2) from the thermophilic eubacterium Thermus thermophilus was crystallized using the hanging-drop vapour-diffusion method. Crystals grew at pH 9.5 in the presence of PEG 8000 and NaCl. A native diffraction data set has been collected at 2.5 A resolution using synchrotron radiation and cryocooling. Crystals belong to the orthorhombic space group P2(1)2(1)2(1), with unit-cell parameters a = 57.3, b = 121.9, c = 166.9 A and V(M) = 3.03 A(3) Da(-1). There is one dimer of M(r) 96 000 per asymmetric unit. A molecular-replacement analysis gave solutions for the rotation and translation functions.
