摘要

A transition state analogue inhibitor, boronic acid benzophenone (BBP) photoprobe, was used to study the differences in the topology of the S1 pocket of chemically modified mutant enzymes (CMMs). The BBP proved to be an effective competitive inhibitor and a revealing active site directed photoprobe of the CMMs of the serine protease subtilisin Bacillus lentus (SBL) which were chemically modified with the hydrophobic, negatively charged and ...
