The complete amino acid sequence of bovine spleen cathepsin S has been determined. The single-chain protein contains 217 residues and has a Mr of 23,682. The primary structure was determined by sequencing of native protein and the peptides obtained by proteolytic cleavage with beta-trypsin, papaya proteinase IV and by chemical cleavage with cyanogen bromide. Comparison of the amino terminal sequences of the heavy and the light chain of bovine cathepsin L with that of bovine cathepsin S clearly indicates that the enzymes are structurally different.
牛脾组织组织蛋白酶S的完整氨基酸序列已被测定。该单链蛋白含有217个氨基酸残基,分子量为23,682。其一级结构通过对天然蛋白、经β-胰蛋白酶和木瓜蛋白酶IV酶解得到的肽段以及经溴化氰化学裂解得到的肽段进行测序来确定。通过比较牛组织蛋白酶L重链和轻链的氨基末端序列与牛组织蛋白酶S的氨基末端序列,清楚地表明这两种酶在结构上是不同的。
