title: Binding of mercury(II) to protein thiol groups: a study of proteinase K and carboxypeptidase Y.
abstract: Chemically modified enzymes have been prepared by incorporating an -Hg-L group into proteinase K and carboxypeptidase Y at the thiol groups of Cys-73 and Cys-341, respectively (L = CN- or I-). The -S-Hg-13CN group has been applied as a spectroscopic label for carbon-13 NMR spectroscopy.
