title: Euphorbia characias latex amine oxidase and peroxidase: interacting enzymes?
abstract: This minireview deals the enzymatic transformation of some amino acids as arginine and ornithine, amines as tyramine, putrescine, spermine and spermidine, and other substances as nitric oxide and thiocyanate. These reactions, catalyzed by two proteins purified from the latex of Euphorbia characias, a copper/quinone containing amine oxidase and a cationic peroxidase, show enzymatic activity interactions probably occurring between these proteins in Euphorbia latex.
