我们报告使用不同的钯配合物,以促进有效的化学蛋白质合成的N-末端和内部半胱氨酸保护基团的选择性去除。利用正交脱保护对,我们通过Pd(0)介导的Alloc脱保护用于一锅多肽连接和Pd(II)Cl 2介导的Acm脱保护以在脱硫后回收天然Cys残基的组合来完成含有三甲基化Lys的组蛋白H3的化学合成。
We report selective removals of N-terminal and internal Cys protecting groups using different palladium complexes to facilitate the efficient chemical protein synthesis. Utilizing the orthogonal deprotection pairs, we accomplished chemical synthesis of histone H3 containing trimethylated Lys through the combination of Pd(0)-mediated Alloc deprotection for one-pot multiple peptide ligation and Pd(II)Cl2-mediated Acm deprotection to recover native Cys residues after desulfurization.
