cysteine residues has been developed and the chemical long-range ligation of these S-acyl peptidesvia 5-, 8-, 11- and 14-membered cyclic transition states has been investigated. Our results include the first examples of successful isopeptide ligations starting from S-acyl peptides containing non-terminal cysteine residues and indicate that the cyclic transition states studied in this present paper are decreasingly
已经开发了一种合成一系列含有内部半胱氨酸残基的S-酰基肽的有效方法,并且这些S-酰基肽通过5-、8-、11- 和 14- 元循环过渡态进行化学远程连接已被调查。我们的结果包括成功的同肽连接的第一个例子,从含有非末端半胱氨酸残基的 S-酰基肽开始,并表明本文研究的循环过渡态按其大小顺序逐渐降低 5>>14>11>> 8 .
