G152A MUTANT OF MYCOBACTERIUM TUBERCULOSIS IRON-SUPEROXIDE DISMUTASE.
Overview
We have refined the X-ray structure of a site-directed G152A mutant of the, iron-dependent superoxide dismutase from Mycobacterium tuberculosis at 2.9, angstroms resolution. The mutation which replaces a glycine residue in a, surface loop with alanine was designed to alter the conformation of this, loop region which has previously been shown to play a crucial structural, role in quaternary interactions within the SOD tetramer. Gly-152 was, targeted as it has dihedral angles (phi = 83.1 degrees, psi = -0.3, degrees) close to the left-handed alpha-helical conformation which is, rarely adopted by other amino acids except asparagine. Gly-152 was, replaced by alanine as it has similar size and polarity, yet has a very, low tendency to adopt similar conformations. X-ray data collection on, ... [(full description)]
