Proteasomes are responsible for the cytoplasmic turnover of the vast majority of proteins including regulatory proteins. We have synthesized lipopeptides a new class of non-covalent inhibitors of the 20S proteasome and assayed their inhibitory capacities. Their ability to inhibit at micromolar concentrations chymotrypsin-like and post-acid activities depends on peptide length (3 or 6 amino acids),
蛋白酶体负责包括调节蛋白在内的绝大多数蛋白质的胞质更新。我们已经合成了脂肽,是一类新型的20S蛋白酶体非共价抑制剂,并测定了其抑制能力。它们在微摩尔浓度下抑制胰凝乳蛋白酶样和后酸活性的能力取决于肽长度(3或6个氨基酸),序列(带正电荷或负电荷的氨基酸)和烷基链长度(C6-C18)。这些结构特征可以变化以选择性地抑制三种蛋白酶体活性中的一种或多种。
