An enzyme from hog kidney was found to catalyze the transfer of the amidine moiety of canavanine to glycine with the formation of glycocyamine. The enzyme was sensitive to heavy metal ions, and was inhibited by p-chloromercuribenzoate. No cofactor requirement was observed, and the optimal pH was about 7.4. It was suggested that an isothiourea-type enzyme-arnidine intermediate complex might be formed.
