Effective Formation of Di- and Tri-γ-glutamates by γ-Glutamyltranspeptidase

Abstract

Usinhg γ-glutamyltranspeptidase, conditions for di- and tri-γ-glutamates synthesis were studied with glutamine and glutamic acid esters as substrates. The reactivity of amino acid esters was higher than for free ones. The efficient conditions were the combination of glutamine ethyl and glutamate diethyl esters with a molar ratio of 1/10 at pH 7-8.
