γ-Glutamyl hydrolases (γGH) catalyze the hydrolysis of γ-linked glutamate residues from the polyglutamyl of folates and antifolates, such as methotrexate (MTX), a widely used anticancer drug. We describe the first crystal structures of the endopeptidase-type γGH (zγGH) from zebrafish and the mutant complexes with MTX(Glu)5 and hydrolyzed MTX(Glu)1, revealing the complete set of key residues involved in hydrolysis as well as the substrate-binding subsites (-1 to +2) ...
