This invention provides modified enzymes comprising one or more amino acid residues replaced by cysteine residues, where the cysteine residues are modified by replacing the thiol hydrogen in the cysteine residues with a substituent group providing a thiol side chain comprising a multiply charged moiety. The enzymes show improved interaction and/or specificity and/or activity with charged substrates.
这项发明提供了一种改良酶,其中一个或多个氨基酸残基被半胱氨酸残基取代,半胱氨酸残基被替换为含有多重带电基团的硫醇侧链取代基,从而改良了酶与带电底物的相互作用和/或特异性和/或活性。
