Bacterial γ-glutamyltranspeptidase: Food and medicinal applications

Hideyuki Suzuki

ABSTRACT:     γ-Glutamyltranspeptidase (GGT) catalyzes the hydrolysis of γ-glutamyl compounds and the transfer of their γ-glutamyl moiety to another amino acids or peptides. We have proposed several applications of this enzyme, especially in food and medicine, for the wellness of humans. These applications depend on the fact that the pH optima of the hydrolysis and transpeptidase reactions are distinctly different in E. coli GGT. The applications of bacterial GGTs are introduced in this review.
