متن کاملKinetic and structural analysis of substrate specificity in two copper amine oxidases from Hansenula polymorpha.
The structural underpinnings of enzyme substrate specificity are investigated in a pair of copper amine oxidases (CAOs) from Hansenula polymorpha (HPAO-1 and HPAO-2). The X-ray crystal structure (to 2.0 A resolution) and steady state kinetic data of the second copper amine oxidase (HPAO-2) are presented for comparison to those of HPAO-1. Despite 34% sequence identity and superimposable active s...
متن کاملInhibition 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 کاملA Xylenol Orange-Based Screening Assay for the Substrate Specificity of Flavin-Dependent para-Phenol Oxidases.
Vanillyl alcohol oxidase (VAO) and eugenol oxidase (EUGO) are flavin-dependent enzymes that catalyse the oxidation of para-substituted phenols. This makes them potentially interesting biocatalysts for the conversion of lignin-derived aromatic monomers to value-added compounds. To facilitate their biocatalytic exploitation, it is important to develop methods by which variants of the enzymes can ...
متن کاملThe Substrate Specificity and Inhibition Char- Acteristics of Two Copper-protein “oxidases””
Evidence has been presented in earlier publications that the rapid oxidation of ascorbic acid in plant press-juices, when exposed to air, is primarily due to the catalytic effect of copper combined with protein. The evidence was of three types : (a) sensitivity to a number of organic and inorganic copper inhibitors, (b) the presence of adequate quantities of copper in the press-juices and enzym...
