Anwendung

D-amino acid oxidase (DAO) is a potential target molecule for the treatment of chronic pain and schizophrenia [1][2]. D-amino acid oxidase is used to oxidize D-amino acids to their corresponding imino acids.

Einheitendefinition

One unit will oxidatively deaminate 1.0 μmole of D-alanine to pyruvate per minute at pH 8.3 at 25 °C, in the presence of a catalase.

Serine racemase (SR) catalyses two reactions: the reversible racemisation of L-serine and the irreversible dehydration of L- and D-serine to pyruvate and ammonia. SRs are evolutionarily related to serine dehydratases (SDH) and degradative threonine deaminases (TdcB). Most SRs and TdcBs

Human D-amino acid oxidase (EC 1.4.3.3; hDAAO) is a peroxisomal flavoenzyme significantly enriched in the mammalian brain. hDAAO has been proposed to play (with serine racemase; EC 5.1.1.18) an essential role in the catabolism of D-serine, an 'atypical' key signalling

Oligolamellar phospholipid vesicles incorporated with d-amino acid oxidase from porcine kidney (OV-DAO) were prepared by encapsulating pre-formed enzyme-bound unilamellar vesicles (UV-DAO) with bilayers of 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC). The bilayer of UV-DAO was composed of POPC, 30 mol% of cholesterol and 15

Inhibition of d-amino acid oxidase (DAAO) activity is a potential target for the treatment of chronic pain. Here we characterized the effects of systemic administration of the DAAO inhibitor 4H-furo[3,2-b]pyrrole-5-carboxylic acid (SUN) in rat models of neuropathic and inflammatory pain.

Questions

  1. Hello, I am doing my research about D-amino acid oxidase from porcine kidney. For further calculations I need molar extinction coefficient of pkDAAO. Maybe You have bigger description or some kind of information about it? Thank You.

    1 answer

    1. There are two extinction coefficient values available:

      Assuming all Cys residues form cystines - 1.935 at 280 nm in water, 0.1% (1 g/L)
      Assuming all Cys residues are reduced - 1.929 at 280 nm in water, 0.1% (1 g/L)
