Publication Abstract from PubMed
PonA2 is one of the two class A Penicillin binding proteins of Mycobacterium tuberculosis, the etiologic agent of tuberculosis. It plays a complex role in mycobacterial physiology and is spotted as a promising target for inhibitors. PonA2 is involved in adaptation of M. tuberculosis to dormancy, an ability which has been attributed to the presence in its sequence of a C-terminal PASTA domain. Since PASTA modules are typically considered as beta-lactam antibiotic binding domains, we determined the solution structure of the PASTA domain from PonA2 and analysed its binding properties versus a plethora of potential binders, including the beta-lactam antibiotics, two typical muropeptide mimics and polymeric peptidoglycan. We show that, despite a high structural similarity with other PASTA domains, the PASTA domain of PonA2 displays different binding properties, as it is not able to bind muropeptides, nor beta-lactams, nor polymeric peptidoglycan. These results indicate that the role of PASTA domains cannot be generalized, as their specific binding properties strongly depend on surface residues, which are widely variable.
