Psychiatry related information on DAO

  • Our aim was to replicate this finding in German schizophrenic patients and to assess whether G72 and DAAO might also contribute to the development of bipolar affective disorder [1].
 

High impact information on DAO

  • The presence of D-amino acid oxidase has been histochemically confirmed in the epithelial cells selected from renal cell suspensions and explants [2].
  • In this medium, D-valine is substituted for L-valine; and only those cells containing D-amino acid oxidase can convert the D-amino acid into its essential L-enantiomer [2].
  • Fibroblasts will not grow in the selective medium, but will proliferate normally if the product of the D-amino acid oxidase reaction is supplied [2].
  • Localization of D-amino acid oxidase on the cell surface of human polymorphonuclear leukocytes [3].
  • DAOC deacylation is carried out by two final enzymatic bioconversions catalyzed by D-amino acid oxidase (DAO) and glutaryl acylase (GLA) yielding 7-ADCA [4].
 

Chemical compound and disease context of DAO

 

Biological context of DAO

 

Anatomical context of DAO

  • Human DAO was stably expressed in Chinese hamster ovary (CHO) cells, and its activity was measured as the amount of hydrogen peroxide detected in the growth medium following feeding the cells with D-serine [10].Associations of DAO with chemical compounds
  • The overall dimeric structure of human DAO is similar to porcine DAO, and the catalytic residues are fully conserved at the re-face of the flavin ring [7].
  • We recently succeeded in purifying human DAO, and found that it weakly binds FAD and shows a significant slower rate of flavin reduction compared with porcine DAO [7].
  • To address this issue, we determined the crystal structure of human DAO in complex with a competitive inhibitor benzoate, at a resolution of 2.5 A [7].
  • DAAO is expressed in human brain where it oxidizes d-serine, a potent activator of N-methyl-D-aspartate type glutamate receptor [11].
  • The isolation of the pure L-amino acid isomer from the enantiomeric mixture, initially obtained using either an open or closed reaction vessel, was achieved using a D-amino acid oxidase/catalase enzyme complex immobilized on a Sepharose support [12].
