Expression, Purification and Crystallization of the Mycobacterium Tuberculosis HSP16.3 Molecular Chaperone Background of Mycobacterium Tuberculosis HSP16.3 HSP16.3, a 16.3 kDa protein from Mycobacterium Tuberculosis, was originally identified as a prominent antigen (Kingston et al., 1987). During the stationary phase
solar energy as the driving force for this global process (Fig. 1). All living organisms also require a source of nitrogen, which is necessary for the synthesis of amino acids, nucleotides, and other compounds. Plants can generally use either ammonia or nitrate as their sole source of nitrogen, but vertebrates must obtain nitrogen in the form
