In this study, we measured the level of … WebWhat is dopamine beta-hydroxylase? Dopamine beta-hydroxylase (DBH) is a copper-containing mono-oxygenase that converts dopamine to norepinephrine in noradrenergic neurons, adrenergic neurons, and adrenal chromaffin cells. Therefore, DBH controls both norepinephrine synthesis and the dopamine/norepinephrine ratio in noradrenergic cells.

WebDBH requires ascorbic acid as cofactor, and ascorbic acid produces H 2 O 2 by autooxidation. Because H 2 O 2 is a potent inhibitor of DBH, catalase must be present in the incubation mixture to protect the enzyme. The inhibition of DBH at high concentrations of copper can also be prevented by catalase. Therefore, in the presence of a large ... WebDopamine is converted into norepinephrine by the enzyme dopamine β-hydroxylase (DBH), with O 2 and L-ascorbic acid as cofactors. Norepinephrine is converted into epinephrine by the enzyme phenylethanolamine N-methyltransferase (PNMT) with S-adenosyl-L-methionine as the cofactor. cushy cello glider bag
