Peptides were efficiently synthesized by the catalysis of chemically engineered protease, thiolsubtilisin, with peptide thioesters as substrate building blocks. The ligation method was successfully applied to the synthesis of a partial sequence of DNA-binding c-Myb protein.
在化学工程蛋白酶硫代硫蓟素的催化下,以肽硫酯为底物构件,高效合成了多肽。这种连接方法被成功应用于合成 DNA 结合 c-Myb 蛋白的部分序列。

A modelstudy of DNA-directed peptide ligation has been developed by transferring fluorescent reporting group from small molecule thioester to a DNA strand (template DNA) in the presence of a thiol-functionalized DNA strand (auxiliary DNA), mimicking the Native Chemical Ligation (NCL) reaction. This DNA-directed transfer shows dependence on the sequence complementarity of the two DNA strands, with
