present a new proteinlabeling method based on the covalentenzymaticphosphocholination of a specific octapeptide amino acid sequence in intact proteins. The bacterial enzyme AnkX from Legionella pneumophila has been established to transfer functional phosphocholine moieties from synthetically produced CDP‐choline derivatives to N‐termini, C‐termini, and internal loop regions in proteins of interest

A bioorthogonalreaction between N,N-dialkylhydroxylamines and cyclooctynes is described. This reaction features a highly regioselective transformation between small, easily functionalizable reaction components with second-order rate constants reaching 84 M–1 s–1. The reaction is orthogonal to the inverse-electron demand Diels–Alder reactions between tetrazine and strained alkenes, and its components
描述了N,N-二烷基羟胺和环辛炔之间的生物正交反应。该反应的特点是在小的、易于官能化的反应组分之间进行高度区域选择性转化,二级速率常数达到 84 M –1 s –1。该反应与四嗪和应变烯烃之间的反电子需求 Diels-Alder 反应正交,其组分在细胞裂解物中表现出极好的稳定性和化学选择性。这种逆向 Cope 消除反应在多产的环加成反应类别之外为生物正交反应纲要引入了一个新成员。

adequately protecting it against cellular nucleophiles. This design preserves the low steric profile of an alkyne and pairs it with a comparably unobtrusive hydroxylamine. The kinetics are on par with those of the fastest strain-promoted azide-alkyne cycloaddition reactions, the products regioselectively formed, the components sufficiently stable and easily installed, and the reaction suitable for cellular
N , N之间的生物正交反应描述了-二烷基羟胺和推拉活化卤代炔烃。我们探索了再杂化效应在激活炔烃中的应用,并且我们表明,当竞争的立体电子和感应因子得到适当平衡时,电子效应在未催化的共轭逆 Cope 消除反应中充分激活线性炔烃,同时充分保护其免受细胞亲核试剂的侵害。这种设计保留了炔烃的低空间分布,并将其与相对不显眼的羟胺配对。动力学与最快的应变促进叠氮化物-炔烃环加成反应相当,产物区域选择性形成,组分足够稳定且易于安装,反应适合细胞标记。
