<sup>11</sup>B NMR studies of an aryl boronic acid bound to chymotrypsin and subtilisin

Baldwin JE, Claridge TDW, Derome AE, Schofield CJ, Smith BD

The binding of aryl boronic acids to α-chymotrypsin and subtilisin has been studied by 11B NMR spectroscopy; evidence is provided for the direct spectroscopic observation of a tetrahedral enzyme/boromate complex. © 1991.
