我们描述了一种新的方法,通过半合成的方法生产组蛋白H_2B与一个工程的索糖酶转肽酶。N-末端修饰的乙酰化、乳糖化和β-羟丁酰化组蛋白H_2BS被掺入核小体中,并作为组蛋白脱乙酰酶复合体和sirtuins的底物。通过这些酶的形式观察到了广泛的速率和位置特异性,这表明在调节染色质结构和表观遗传学方面具有不同的生物学作用。
We describe a new method to produce histone H2B by semisynthesis with an engineered sortase transpeptidase. N-Terminal tail site-specifically modified acetylated, lactylated, and β-hydroxybutyrylated histone H2Bs were incorporated into nucleosomes and investigated as substrates of histone deacetylase (HDAC) complexes and sirtuins. A wide range of rates and site-specificities were observed by these enzyme forms suggesting distinct biological roles in regulating chromatin structure and epigenetics.
