The complete amino acid sequence of beta-purothionin, a low molecular weight, very basic, protein isolated from wheat endosperm material, has been determined. beta-purothionin is toxic to some bacteria, to yeasts, and to animals when injected. The protein contains 45 amino acid residues and has a molecular weight of 4913. The 8 cysteine and 10 basic residues are distributed throughout the molecule. The primary structure of the protein shows considerable homology to those of the viscotoxins, which are toxic, small, basic proteins found in the leaves and stems of European mistletoe (Viscum album L.).
从小麦胚乳材料中分离出的一种低分子量、强碱性蛋白质β-硫堇的完整氨基酸序列已被确定。β-硫堇对某些细菌、酵母以及注射时对动物有毒性。该蛋白质含有45个氨基酸残基，分子量为4913。8个半胱氨酸残基和10个碱性残基分布于整个分子。该蛋白质的一级结构与槲寄生毒素有相当的同源性，槲寄生毒素是在欧洲槲寄生（Viscum album L.）的叶和茎中发现的有毒、小分子、碱性蛋白质。
