TAILIEUCHUNG - Báo cáo khoa học: Structural insight into the evolutionary and pharmacologic homology of glutamate carboxypeptidases II and III

Glutamate carboxypeptidase III (GCPIII) is a metalloenzyme that belongs to the transferrin receptor⁄glutamate carboxypeptidase II (GCPII; EC ) superfamily. GCPIII has been studied mainly because of its evo-lutionary relationship to GCPII, an enzyme involved in a variety of neuro-pathologies and malignancies, such as glutamatergic neurotoxicity and prostate cancer. | Structural insight into the evolutionary and pharmacologic homology of glutamate carboxypeptidases II and III Klara Hlouchova1 2 Cyril Barinka3 Jan Konvalinka1 2 and Jacek Lubkowski3 1 Gilead Sciences and IOCB Research Centre Institute of Organic Chemistry and Biochemistry Academy of Sciences of the Czech Republic Prague Czech Republic 2 Department of Biochemistry Faculty of NaturalScience Charles University Prague Czech Republic 3 Center for Cancer Research NationalCancer Institute at Frederick MD USA Keywords GCPIII M28 family metallopeptidase NAALADase II prostate specific membrane antigen Correspondence J.
