| + | [[http://www.uniprot.org/uniprot/FOLH1_HUMAN FOLH1_HUMAN]] Has both folate hydrolase and N-acetylated-alpha-linked-acidic dipeptidase (NAALADase) activity. Has a preference for tri-alpha-glutamate peptides. In the intestine, required for the uptake of folate. In the brain, modulates excitatory neurotransmission through the hydrolysis of the neuropeptide, N-aceylaspartylglutamate (NAAG), thereby releasing glutamate. Isoform PSM-4 and isoform PSM-5 would appear to be physiologically irrelevant. Involved in prostate tumor progression. Also exhibits a dipeptidyl-peptidase IV type activity. In vitro, cleaves Gly-Pro-AMC. | ||

| + | Inhibition of glutamate carboxypeptidase II (GCPII) is effective in preclinical models of neurological disorders associated with excessive activation of glutamatergic systems. Here we report synthesis, structural characterization, and biological activity of new hydroxamic acid-based inhibitors with nanomolar affinity for human GCPII. Crystal structures of GCPII/hydroxamate complexes revealed an unprecedented binding mode in which the putative P1' glutarate occupies the spacious entrance funnel rather than the conserved glutamate-binding S1' pocket. This unique binding mode provides a mechanistic explanation for the structure-activity relationship data, most notably the lack of enantiospecificity and the tolerance for bulky/hydrophobic functions as substituents of a canonical glutarate moiety. The in vivo pharmacokinetics profile of one of the inhibitors will be presented along with analgesic efficacy data from the rat chronic constrictive injury model of neuropathic pain. | ||
