In eukaryotes, hydrogen sulphide acts as a signalling molecule and cytoprotectant. Hydrogen sulphide is known to be produced from L-cysteine by cystathionine β-synthase, cystathionine γ-lyase and 3-mercaptopyruvate sulfurtransferase coupled with cysteine aminotransferase. Here we report an additional biosynthetic pathway for

D-Amino acid oxidase (DAAO), a FAD-dependent peroxisomal flavoenzyme that catalyzes oxidation of D-amino acids to hydrogen peroxide, is distributed in the spinal cord almost exclusively expressed within astrocytes. The present study aims to explore potential contributions of spinal DAAO to

Fermented foods produced using edible microorganisms have been consumed worldwide since ancient times. Microorganisms produce some healthy functional substances. Recently, many people have been attracted to the notion that D-body amino acids have healthy functional effects. D-body amino acids convert

D-Amino acid oxidase (DAO) has been established to be involved in the oxidation of D-serine, an allosteric activator of the N-methyl-D-aspartate-type glutamate receptor in the brain, and to be associated with the onset of schizophrenia. The effect of risperidone, a

If I store it at -4 degrees Celsius instead of -20 degrees Celsius, will the enzyme denature so much that it cannot be used? Also, if I expose it to room temperature for use in an experiment and then store it at -4 degrees Celsius, will it be usable again

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-
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)Please see the link below to review this and additional information available at Expasy:
