Twelve positions in a β-lactamase that can expand its substrate spectrum with a single amino acid substitution.
The continuous evolution of β-lactamases resulting in bacterial resistance to β-lactam antibiotics is a major concern in public health, and yet the underlying molecular basis or the pattern of such evolution is largely unknown. We investigated the mechanics of the substrate fspectrum expansion of th...
