Crystals of the chemically synthesized acceptor stem of tRNAAla from Escherichia coli diffracting to high resolution.
The acceptor stem of tRNA(Ala) from E. coli has been chemically synthesized and crystallized. This duplex contains a G.U base pair in position 3-70, which is the main identity element for alanyl-tRNA synthetase from E. coli. The crystals are stable in the X-ray beam for a long period of time and diffract to 1.7 A resolution. The monoclinic crystals reveal a C2 space group with a = 35.0, b = 47.5, c = 26.2 A, beta = 102.3 degrees and one acceptor stem per asymmetric unit.
