鉴定了大鼠胃组织蛋白酶E的氨基末端结构,并与人胃组织蛋白酶E原和其他天冬氨酸蛋白酶的相应区域进行了比较。比对结果显示,在天冬氨酸蛋白酶中,组织蛋白酶E的氨基末端结构最长,表明该酶的激活肽(前肽)长度为39个残基。低聚糖单位分析表明,大鼠组织蛋白酶E具有一个n连接的碳水化合物单位,可能是高甘露糖型的。没有证据表明大鼠组织蛋白酶E中存在o链糖。
The amino-terminal structure of rat gastric cathepsin E was identified and compared with the corresponding regions of human procathepsin E and other aspartic proteinases. The alignment revealed that cathepsin E has the most extended amino-terminal structure in aspartic proteinases, thus suggesting that the activation peptide (propeptide) of the human enzyme is 39-residues long. Analysis of oligosaccharide units suggested that rat cathepsin E possesses one N-linked carbohydrate unit, probably of the high mannose type. No evidence was obtained for the presence of O-linked sugars in rat cathepsin E.
