Crystal Structure Determination of E. coli Elongation Factor, Tu using a Twinned Data Set

Overview

Escherichia coli elongation factor Tu-GDP (EF-Tu-GDP) was crystallized in, the presence of novel inhibitors. The only crystals which could be grown, were epitaxially as well as merohedrally twinned, highly mosaic and, diffracted to a resolution of 3.4 A in space group P3(1)21, with unit-cell, parameters a = b = 69.55, c = 169.44 A, alpha = beta = 90, gamma = 120, degrees . To determine whether an inhibitor was present in the crystal, a, poor-quality X-ray diffraction data set had to be processed. The, three-dimensional structure was ultimately solved and the original, question answered. The results also reveal a new type of dimer packing for, EF-Tu-GDP.
