Abstract

Conditions for the thermolysin- or papain-catalyzed peptide bond formation between tert-butyloxycarbonyl-O4-sulfotyrosine and leucine or methionine phenylhydrazide have been found. Acylation of O4-sulfotyrosine phenylhydrazide with tert-butyloxycarbonylphenylalanine methyl ester was catalyzed by α-chymotrypsin. Tert-butyloxycarbonyl-O4-phosphotyrosyl-leucine phenylhydrazide was prepared by thermolysin-catalyzed reaction.
