赖氨酸ε- N - L-乳酸化是一种新发现的翻译后修饰。在此,我们介绍了细菌和哺乳动物细胞中 ε- N - L-乳酰赖氨酸的遗传编码,从而可以制备位点特异性ε- N - L-乳酰化重组蛋白,并构建用于检测活细胞中去乳酰酶的荧光和发光探针. 使用这些探针,我们证明了 sirtuin 1 作为非组蛋白的潜在脱乳糖酶。

corresponding carboxylic acids (acetic acid, formic acid, lactic acid and glyceric acid) accumulated over time. Both Nε-lysine amides and carboxylic acids were thus determined as stable Maillard end products. Results of model incubations suggested the synthesis of amides to be mechanistically closely related to the formation of their corresponding carboxylic acids by β-dicarbonyl cleavage. Due to the
Lysine ε-N-L-lactylation is a newly discovered post-translational modification. Herein we present the geneticencoding of ε-N-L-lactyllysine in bacterial and mammalian cells, allowing the preparation of site-specifically ε-N-L-lactylated recombinant proteins and the construction of fluorescent and luminescent probes for detecting delactylases in living cells. Using these probes, we demonstrate sirtuin
