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 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...
