摘要:Effect of biogenic amines on the hog kidney histaminase was examined by the Warburg manometric technique and it was clarified that putrescine, cadaverine, agmatine, and γ-aminobutyric acid effected strong cross inhibition, arcaine and methylguanidine a strong inhibition, and trimethylamine and trimethylamine oxide effected a weak inhibition, while choline showed practically no effect. Phosphorylethanolamine and betaine, on the other hand, indicated a slight acceleration and tyramine and phosphorylcholine effected a strong acceleration.
