ABSTRACT:
The invention relates to methods and mutation linkers to modify DNA, to methods for producing libraries containing a multiplicity of modified DNA, and to methods for using such libraries for screening modified proteins encoded by such DNA. The DNA targeted for modification typically encodes a polypeptide such as an enzyme. The libraries are used to determine the effect of such modification or the interaction of the modified polypeptides with a target. In preferred embodiments, the invention relates to methods for making and using libraries containing DNA encoding modified antibiotic hydrolases to screen antibiotics against one or more of the modified antibiotic hydrolases produced by such libraries. Susceptibility or lack of susceptibility of an antibiotic to neutralization provides an indication of whether wild-type antibiotic hydrolases are likely to mutate to confer resistance to the antibiotic.
