Metal‐based bioconjugation linkages represent a little‐studied approach to protein functionalization that provides novel reactivity, stability, and function. Described is an organometallic bioconjugation, employing rhodium(III) salts, to link boronic acids with tyrosine residues by an arene complex. Both peptides and proteins are amenable to the mild bioconjugation in aqueous media, allowing incorporation
基于金属的生物缀合键代表了一种尚未被研究的蛋白质功能化方法,该方法提供了新的反应性,稳定性和功能。描述了使用铑(III)盐的有机金属生物共轭,其通过芳烃配合物将硼酸与酪氨酸残基连接。肽和蛋白质都适合在水性介质中进行温和的生物缀合,从而允许引入有用的功能,例如亲和柄或荧光团。由于无机键的亚稳定性,缀合物易于被亲核氧化还原介质裂解,但对典型的生物学条件稳定。
