R02150 ]
Reaction(KEGG)
Substrate
Product
(imidazol-4-yl)acetaldehyde;
NH3 [CPD:
C00014 ];
H2O2 [CPD:
C00027 ]
Comment
A group of enzymes that oxidize diamines, such as histamine, and also some primary monoamines but have little or no activity towards secondary and tertiary amines. They are copper quinoproteins (2,4,5-trihydroxyphenylalanine quinone) and, like EC
1.4.3.21 (primary-amine oxidase) but unlike EC
1.4.3.4 (monoamine oxidase), they are sensitive to inhibition by carbonyl-group reagents, such as semicarbazide.
History
EC 1.4.3.22 created 2007 (EC 1.4.3.6 created 1961, part-incorporated 2008)
Pathway
ec00330 Arginine and proline metabolism
