摘要

The enzymatic cleavage of amino acid phenylhydrazides with the enzyme tyrosinase (EC 1.14. 18.1) offers a new, mild, and selective method for C-terminal deprotection of peptides. The advantages of the described methodology are the very mild oxidative removal of the protecting group at room temperature and pH 7, a high chemo-and regioselectivity, and the availability of the biocatalyst. Even in oxygen-saturated solution, the oxidation of sensitive ...
