Cloning, expression, purification, crystallization and preliminary X-ray crystallographic analysis of initiation factor 1 from Mycobacterium tuberculosis.

ABSTRACT: Initiation factor 1 (IF-1; Rv3462c) from Mycobacterium tuberculosis, a component of the 30S initiation complex, was cloned and heterologously expressed in Escherichia coli. The protein was purified by affinity and size-exclusion chromatography and crystallized. A complete data set has been collected to high resolution. The crystals belonged to space group P2(1)2(1)2, with two molecules per asymmetric unit which are related by translational symmetry.
