PER-2 has been the second most prevalent acquired extended spectrum ß-lactamase in clinical isolates of enterobacteria in Argentina. Even if natural mutants of PER-2 have not yet been reported, constant selective pressure posed by the extensive antibiotic and inhibitors use, and the known evolutionary outcomes for other ?-lactamase families, we wondered about the actual possibility to evolve by point mutations that further improve or modify its catalytic efficiency and/or decrease susceptibility to inhibitors. By means of in silico modeling, we observed that Arg220 in PER-2 is located at equivalent spatial position than Arg244 in TEM-1/SHV-1. As inhibitor resistant TEM/SHV can arise by single mutations in this residue, we postulated that si...
