Název v původním jazyce

Structural and biochemical characterization of the folyl-poly-gamma-L-glutamate hydrolyzing activity of human glutamate carboxypeptidase II

Popis výsledku v původním jazyce

In addition to its well-characterized role in the central nervous system, human glutamate carboxypeptidase II (GCPII; Uniprot ID Q04609) acts as a folate hydrolase in the small intestine, participating in the absorption of dietary polyglutamylated folates (folyl-n-gamma-L-glutamic acid), which are the provitamin form of folic acid (also known as vitamin B-9). Despite the role of GCPII as a folate hydrolase, nothing is known about the processing of polyglutamylated folates by GCPII at the structural or enzymological level. Moreover, many epidemiologic studies on the relationship of the naturally occurring His475Tyr polymorphism to folic acid status suggest that this polymorphism may be associated with several pathologies linked to impaired folate metabolism. In the present study, we report: (a) a series X-ray structures of complexes between a catalytically inactive GCPII mutant (Glu424Ala) and a panel of naturally occurring polyglutamylated folates; (b) the X-ray structure of the His475
