MutT proteins’ sequences alignment. Mycobacterium tuberculosis Rv2985(MutT1), Rv1160(MutT2), Rv0413(MutT3), and Rv3908(MutT4) were selected from the M. tuberculosis genome because of their annotation or after a BLAST analysis. These sequences were compared to Escherichia coli mutT by using alignments available from: http://www.biochem.uthscsa.edu/~barnes/mutt.html. The detected region of similarity is shown here. #, absolutely conserved residues; *, residues that are strongly conserved and that
