The complete amino acid sequence of protein SCMKB-IIIB4 is presented. It is closely related to the sequence of protein SCMKB-IIIB3 (Haylett, Swart & Parris, 1971) differing in only four positions. The peptic and thermolysin peptides of protein SCMKB-IIIB4 were analysed by the dansyl-Edman method (Gray, 1967) and by tritium-labelling of C-terminal residues (Matsuo, Fujimoto & Tatsuno, 1966). This protein is the third member of a group of high-sulphur wool proteins with molecular weight of about 11400. It consists of 98 residues and has acetylalanine and carboxymethylcysteine as N- and C-terminal residues respectively.
本文给出了蛋白质SCMKB-IIIB4的完整氨基酸序列。它与蛋白质SCMKB-IIIB3的序列(Haylett、Swart和Parris,1971年)密切相关,仅在四个位置有所不同。采用丹磺酰-埃德曼法(Gray,1967年)和C末端残基的氚标记法(Matsuo、Fujimoto和Tatsuno,1966年)对蛋白质SCMKB-IIIB4的胃蛋白酶和嗜热菌蛋白酶肽段进行了分析。该蛋白质是一组分子量约为11400的高硫羊毛蛋白中的第三个成员。它由98个残基组成,N末端残基为乙酰丙氨酸,C末端残基分别为羧甲基半胱氨酸。
