Descrizione generale
Research area: Cell Signaling
Choline oxidase from Arthrobacter sp. is a flavoprotein, which is a member of the glucose–methanol–choline (GMC). The codA gene encodes the choline oxidase enzyme.
Choline oxidase from Arthrobacter sp. is a flavoprotein, which is a member of the glucose–methanol–choline (GMC). The codA gene encodes the choline oxidase enzyme.
Applicazioni
Choline oxidase from Arthrobacter sp. has been used in the enzymatic determination of choline in milk using a flow injection analysis (FIA) system with potentiometric detection. It has been used for fluorescent detection of choline released during autotaxin (ATX) activity in conditioned media and plasma.
Azioni biochim/fisiol
Choline oxidase from Arthrobacter sp. is a flavoprotein, which is a member of the GMC-oxidoreductase family. The enzyme catalyzes the four-electron-oxidation of choline to glycine betaine via the intermediate betaine aldehyde, in two sequential FAD-dependent reaction steps. The enzyme is useful for enzymatic determination of phosphatidylcholine by coupling with phospholipase D or determination of sphingomyelin by coupling with sphingomyelinase and for cholinesterase activity assays.Choline oxidase (COD) mediating glycine betaine biosynthetic pathway plays a vital role in creating stress resistant transgenic plants.
Definizione di unità
One unit will form 1 μmole of H2O2 with oxidation of 1 μmole of choline to betaine aldehyde per min at pH 8.0 at 37 °C. Note: During the conversion of choline to betaine by choline oxidase, 2 μmoles of H2O2 are produced for every μmole of choline.
Nota sulla preparazione
It is recommended to reconstitute choline oxidase in phosphate buffer at pH 7.5 supplemented with 10mM EDTA. Reconstituted material can be stored at 2-8 °C for at least 2 weeks.
