Mycobacterium tuberculosis (Mtb), the causative agent of the disease tuberculosis, is an ancient pathogen and a major cause of death worldwide. Although various virulence factors of M. tb have been identified, its pathogenesis remains incompletely understood. TlyA is a virulence factor that is evolutionarily conserved in many gram-positive bacteria, but its full length structure and function in the pathogenesis of infection with Mtb has not been elucidated. In the present study, we cloned, expressed and purified N-terminal domain of tlyA, which play a crucial role in the binding of the co-substrate S-adenosyl-L-methionine. We characterized the protein by SDS-PAGE and Circular Dichroism. TlyA model generated using tlyA crystal structure, clearly indicates E59 separates between N-terminal domain (NTD) and C-terminal domain (CTD).
