Generic protein structure example

DBH-like monooxygenase protein 1, also known as monooxygenase X, is an enzyme that in humans is encoded by the MOXD1 gene.[1][2]

DBH-like 1 maintains many of the structural features of dopamine beta-monooxygenase DBH.[3] Since Peptidylglycine alpha-hydroxylating monooxygenase (PHM; EC 1.14.17.3) is homologous to dopamine beta-monooxygenase (DBM; EC 1.14.17.1)[4] this concerns a structural basis for a new family of copper type II, significantly specific for ascorbate-dependent monooxygenases[4] based on the corresponding mouse homolog.[2] The pathway of catecholamine synthesis is a possible catecholamine-binding metabolic copper[5] enzyme domain, a neuron-like property encoding MOX without a signal sequence enzyme metabolism resolving the monooxygenase X chemical pathway[5] of an unknown substrate,[2] exogenous MOX is not secreted, and it localizes throughout the endoplasmic reticulum,[5] in both endocrine or nonendocrine cells.[5]

Deficiency

DBH deficiency has been treated effectively with L-threo-3,4-dihydroxyphenylserine (DOPS).[6]
