Quinoprotein amine oxidases - a new group of ubiquitous enzymes playing the key role in degradation of cellular polyamines.
Original language description
Amine oxidases (EC 1.4.3.6) that contain copper/topa quinone cofactor belong to the new protein group of quinoproteins emerging in the recent years. This review brings together information about general properties of the enzymes and their physiological functions. In plants, these enzymes are involved in plant development and senescence, reduce the concentration of toxic amines produced during exposure to stress conditions, provide hydrogen peroxide for wall stiffening and lignification and precursory compounds for biosynthesis of some alkaloids. Major attention is being paid to the structure of the active site of the enzymes that contains copper ions and a posttranslationally modified tyrosyl residue, topa quinone. Three-dimensional structures recentlyobtained for several amine oxidases by X-ray diffraction analysis of the respective crystals provided important structural information about unique protein folding of the native enzyme and molecular arrangement of the active site.
