Among these, the copper amine oxidases catalyze the oxidative deamination of primary amines utilizing a type(II) copper center and 2,4,5-trihydroxyphenylalanine quinone (TPQ), a covalent cofactor derived from the post-translational modification of an active site tyrosine. Previous studies established...

Previous studies of wild-type and mutant forms of a recombinant copper amine oxidase from Hansenula polymorpha, expressed in Saccharomyces cerevisiae, have indicated a self-processing mechanism for 2,4,5-trihydroxyphenylalanine (topa) quinone biogenesis involving the active site copper (Cai, D., and...
2,4,5-Trihydroxyphenylalanine (TOPA) in aqueous solution has been shown to form an non-N-methyl-D-aspartate (non-NMDA) agonist and neurotoxin, TOPA quinone. We examined whether the endogenous chemical reductant glutathione (GSH) could abolish the agonist properties of TOPA and block its ...
