Cefotaxime 111-121 TEM-1 beta-lactamase Escherichia coli 41-61 3884565-3 1985 When an E. coli strain producing high levels of TEM-1 beta-lactamase constituted 6% or more of the population, the whole colony was resistant to cefamandole, but still sensitive to cefotaxime, cefoxitin or imipenem. Cefotaxime 181-191 TEM-1 beta-lactamase Escherichia coli 48-68 11224569-4 2001 To test this theory, TEM-1 beta-lactamase was evolved using a hypermutator E. coli-based directed evolution technique with cefotaxime selection. Cefotaxime 123-133 TEM-1 beta-lactamase Escherichia coli 21-41 10699880-4 2000 We applied this approach to TEM-1 beta-lactamase which confers resistance to 0.05 mg/L of the antibiotic cefotaxime. Cefotaxime 105-115 TEM-1 beta-lactamase Escherichia coli 28-48
