Crystals of the chemically synthesized acceptor stem of tRNAAla from Escherichia coli diffracting to high resolution
Abstract:
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.

X-ray Diffraction of Biological Samples
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal crystal...
