Serine 90-96 hypothetical protein Escherichia coli 36-41 9174192-6 1997 This enzyme differed from TEM-1 (blaT-1B gene) by four amino acid substitutions: Met-->Leu-69, Glu-->Lys-104, Gly-->Ser-238 and Asn-->Asp-276. Serine 125-128 hypothetical protein Escherichia coli 26-31 16262787-6 2005 Site-directed mutagenesis of the catalytic Ser of TEM-1, but not Oxa-3, abolished the biofilm defect, while disruption of either TEM-1 or Oxa-3 expression restored wild-type levels of biofilm formation. Serine 43-46 hypothetical protein Escherichia coli 50-55 14534312-2 2003 In TEM-1 and SHV-1, the common class A beta-lactamases, alterations at Ser-130 confer resistance to inactivation by the beta-lactamase inhibitors, clavulanic acid, and tazobactam. Serine 71-74 hypothetical protein Escherichia coli 3-8 8239618-3 1993 Both TEM-10 sequences differed from TEM-1 by substitutions of Ser-162 and Lys-237. Serine 62-65 hypothetical protein Escherichia coli 5-10 8877532-3 1996 The blaIRT gene differs from blaTEM-2 gene by one point mutation which leads to the amino-acid substitution Arg-->Ser at position 244, as observed for the original IRT-2 enzyme derived from TEM-1 reported in Escherichia coli. Serine 117-120 hypothetical protein Escherichia coli 193-198 8067751-5 1994 The doubly mutated derivative of the TEM-1 enzyme (Ser-164/Ser-244) retains the characteristics of the Ser-164 mutant enzyme, i.e., enhanced activity against ceftazidime and sensitivity to inactivation by clavulanate. Serine 51-54 hypothetical protein Escherichia coli 37-42 35052944-5 2022 Here, by using ampD and ampE mutants of E. coli, we attempted to elucidate the effects of ampD and ampE on the expression of serine-BLAs originating from Enterobacteriaceae, viz., CTX-M-15, TEM-1 and OXA-2. Serine 127-133 hypothetical protein Escherichia coli 192-197
