Properties of Mutant SHV-5 β-Lactamases Constructed by Substitution of Isoleucine or Valine for Methionine at Position 69
The effect of replacement of Met-69 by Ile or Val on the properties of the extended-spectrum β-lactamase SHV-5 was studied. Mutant enzymes were constructed by site-specific mutagenesis and expressed under isogenic conditions in Escherichia coli DH5α cells. Compared with SHV-5, the mutant β-lactamase...
