The primary structure of protein S8 from the 30S subunit of Escherichia coli ribosomes has been determined by sequencing the peptides derived from tryptic, chymotryptic, thermolytic and staphylococcal protease digestion of the protein. Protein S8 has 129 amino acid residues which result in a molecular weight of 13996. The N-terminal part of the sequence up to position 68 is in complete agreement with the reported sequence data[1,2]. However, differences exist in the C-terminal half, where an additional hydrophobic tryptic peptide has been found.
通过对大肠杆菌核糖体30S亚基中蛋白质S8经胰蛋白酶、胰凝乳蛋白酶、嗜热菌蛋白酶和葡萄球菌蛋白酶消化产生的肽段进行测序,确定了该蛋白质的一级结构。蛋白质S8有129个氨基酸残基,分子量为13996。该序列N端至第68位的部分与已报道的序列数据完全一致[1,2]。然而,C端的后半部分存在差异,在该区域发现了一个额外的疏水性胰蛋白酶肽段。
