一般說明
胰蛋白酶分子有两个结构域：一个与酶的活性位点和色氨酸残基有关；另一种与 8-苯胺萘-1-磺酸结合有关。
胰蛋白酶是一种丝氨酸蛋白酶。胰腺可产生前体胰蛋白酶原并将其分泌到肠中。肠粘膜中的肠激酶可将胰蛋白酶原转化为胰蛋白酶。[1]

Cellular heterogeneity is pervasive and of paramount importance in biology. Single-cell analysis techniques are indispensable for understanding the heterogeneity and functions of cells. Low-copy-number proteins (fewer than 1,000 molecules per cell) perform multiple crucial functions such as gene expression, cellular
