Expression, purification and preliminary crystallographic analysis of recombinant human small glutamine-rich tetratricopeptide-repeat protein.

ABSTRACT: Human small glutamine-rich tetratricopeptide-repeat protein (hSGT) is a 35 kDa protein implicated in a number of biological processes that include apoptosis, cell division and intracellular cell transport. The tetratricopeptide-repeat (TPR) domain of hSGT has been cloned and expressed in Escherichia coli and purified. Here, the crystallization and preliminary diffraction analysis of the TPR domain of hSGT is reported. X-ray diffraction data were processed to a resolution of 2.4 A. Crystals belong to space group P2(1)2(1)2, with unit-cell parameters a = 67.82, b = 81.93, c = 55.92 A, alpha = beta = gamma = 90 degrees .
