ABSTRACT A new natural TEM-2 derivative, named TEM-72, was identified in aProteus mirabilis strain and in a Morganella morganii strain isolated in Italy in 1999. Compared to TEM-1, TEM-72 contains the following amino acid substitutions: Q39K, M182T, G238S, and E240K. Kinetic analysis showed that TEM-72 exhibits an extended-spectrum activity, including activity against oxyimino-cephalosporins and aztreonam. Expression ofblaTEM-72 in Escherichia coli was capable of decreasing the host susceptibility to the above drugs.
