Inhibition of chickpea seedling copper amine oxidases by tetraethylenepentamine
Copper amine oxidases are important enzymes, which contribute to the regulation of mono- and polyamine levels. Each monomer contains one Cu(II) ion and 2,4,5-trihydroxyphenylalanine (TPQ) as cofactors. They catalyze the oxidative deamination of primary amines to aldehydes with a ping-pong mechanism consisting of a transamination. The mechanism is followed by the transfer of two electrons to mol...

متن کاملCopper-Containing Amine Oxidases and FAD-Dependent Polyamine Oxidases Are Key Players in Plant Tissue Differentiation and Organ Development
Plant polyamines are catabolized by two classes of amine oxidases, the copper amine oxidases (CuAOs) and the flavin adenine dinucleotide (FAD)-dependent polyamine oxidases (PAOs). These enzymes differ to each other in substrate specificity, catalytic mechanism and subcellular localization. CuAOs and PAOs contribute to several physiological processes both through the control of polyamine homeost...
متن کاملCompetitive inhibition of copper amine oxidases by vitamin B hydrochloride in chickpea
Copper amine oxidases (CAOs) catalyse the oxidative de-amination of biogenic amines which are ubiquitous compounds essential for cell growth and proliferation. The enzymes are homodimers containing both topaquinone and a Cu(II) ions as cofactors at the active site of each subunit. After extraction and purification of chickpea (cicer arietinum) amine oxidase by chromatoghraphy, Km and Vmax of th...
