Three new crystal forms of the complex between yeast tRNAAsp and aspartyl-tRNA synthetase have been produced. The best crystals, obtained after modifying both purification and crystallization conditions, belong to space group P2(1)2(1)2(1) and diffract to 2.7 A. Unit cell parameters are a = 210.4 A, b = 145.3 A and c = 86.0 A (1 A = 0.1 nm), with one dimeric enzyme and two tRNA molecules in the asymmetric unit.
