DBH-like monooxygenase protein 1, also known as monooxygenase X, is an enzyme that in humans is encoded by the MOXD1 gene. ^{[5] [6]}

DBH-like 1 maintains many of the structural features of dopamine beta-monooxygenase DBH. ^[7] Since Peptidylglycine alpha-hydroxylating monooxygenase (PHM; EC 1.14.17.3) is homologous to dopamine beta-monooxygenase (DBM; EC 1.14.17.1) ^[8] this concerns a structural basis for a new family of copper type II, significantly specific for ascorbate-dependent monooxygenases ^[8] based on the corresponding mouse homolog. ^[6] The pathway of catecholamine synthesis is a possible catecholamine-binding metabolic copper ^[9] enzyme domain, a neuron-like property encoding MOX without a signal sequence enzyme metabolism resolving the monooxygenase X chemical pathway ^[9] of an unknown substrate, ^[6] exogenous MOX is not secreted, and it localizes throughout the endoplasmic reticulum, ^[9] in both endocrine or nonendocrine cells. ^[9]

Deficiency

DBH deficiency has been treated effectively with L-threo-3,4-dihydroxyphenylserine (DOPS). ^[10]
