Using biophysical modeling and bioinformatics analysis, researchers show significant evolution in the structural characteristics and physiochemical properties of the antibiotic-destroying enzyme beta-lactamase across bacterial families, but also find that these evolutionary characteristics do not appear to be specifically related to different versions of antibiotic resistance. The results are far from reassuring, since they show that new antibiotic resistance is relatively easy for bacteria to evolve.
