Crystal structure of the C-terminal domain hexamer of ArgR from Mycobacterium tuberculosis
Overview
The gene product of an open reading frame Rv1657 from Mycobacterium, tuberculosis is a putative arginine repressor protein (ArgR), a, transcriptional factor that regulates the expression of, arginine-biosynthetic enzymes. Rv1657 was expressed and purified and a, C-terminal domain was crystallized using the hanging-drop vapour-diffusion, method. Diffraction data were collected and processed to a resolution of, 2.15 A. The crystals belong to space group P1 and the Matthews coefficient, suggests that the crystals contain six C-terminal domain molecules per, unit cell. Previous structural and biochemical studies on the arginine, repressor proteins from other organisms have likewise shown the presence, of six molecules per unit cell.
