In oder to clarify the reaction products of γ-guanido- and γ-guanido-β-oxy-butyric acid by heteroarginase obtained from rabbit (small) intestine mucous membrane and liver, in vitro experiments have been conducted. It was demonstrated by paper chromatography of reaction mixtures that γ-amino-butyric acid and urea, and γ-amino-β-oxy-butyric acid and urea, were formed respectively in the former and latter.
