Dopamine beta-hydroxylase-related (IPR000945)

Short name: DBH-rel

Family relationships

Description

This family represents Dopamine beta-monooxygenase (DBH) and related enzymes, including tyramine beta-hydroxylase, MOXD1 homologue 1/2 and DBH-like monooxygenase protein 1/2 [PMID: 8656284].

DBH, also known as Dopamine beta-hydroxylase, is a class of ascorbate-dependent enzymes from the catecholamine biosynthetic pathway that requires copper as a cofactor and uses ascorbate as an electron donor. DBH catalyses the conversion of dopamine to the neurotransmitter norepinephrine:

3,4-dihydroxyphenethylamine + ascorbate + O2 = noradrenaline + dehydroascorbate + H2O

DBH exists in both soluble (in chromaffin granules) and membrane bound forms. The protein functions as a homotetramer [PMID: 2295597, PMID: 6998654].
