辅脂酶(Colipase) 是一种蛋白质辅酶,可提升胰脂酶英语lipase的酵素活性。本蛋白的前体前辅脂酶(procolipase)由胰腺所分泌,此时并没有酵素活性。前辅脂酶进入肠道后,会被胰蛋白酶分解为辅脂酶,此时方有功能。辅脂酶的功能是为了防止胆盐在十二指肠内抑制脂肪酶水解三酰甘油

在人类中,辅脂酶由 CLPS 基因翻译而得。[5]

蛋白质结构域

辅脂酶是胰脂酶可有效提升胰脂酶的功能,影响人体吸收三酸甘油脂的能力。辅脂酶会与胰脂酶的无酵素活性的C端结合,稳定其激活态。辅脂酶还能提高其结合位点的疏水性。 相关的蛋白质结构研究已解开其单体及复合体立体结构的功能[6][7]

辅脂酶是一个具有五个保守双硫键的小型蛋白质。其结构类似Dickkopf蛋白[7]
