Putative N-terminal processing sites for MTB ClpP1 and ClpP2. The N-terminal sequences of MTB ClpP1 (H37Rv strain, gi: 41353667) and ClpP2 (H37Rv strain, gi: 2791500) were aligned with that of E. coli ClpP (gi: 89107307) and with those of S. coelicolor ClpP1 (gi: 10280519) and ClpP2 (10280518) respectively using ClustalW program http://www.ebi.ac.uk/Tools/msa/clustalw2. The propeptides of E. coli ClpP and Streptomyces ClpP1 and ClpP2 are written in italics and the first residues of mature ClpPs are indicated in bold. The putative first residues of MTB ClpP1 and ClpP2 are written in bold and indicated with an asterisk.
