An NAD featuring an adenosyl 4'-azido functions as a general substrate for poly-ADP-ribose polymerases. Its derived mono- and poly-ADP-ribosylated proteins can be adequately recognized by distinct ADP-ribosylation-specific readers. This molecule represents the first ribose-functionalized NAD with versatile activities across different ADP-ribosyltransferases and provides insight into developing new probes for ADP-ribosylation.
一种带有腺嘌呤基 4'-叠氮化物的 NAD 可以作为多聚 ADP-核糖聚合酶的通用底物。其衍生的单聚和多聚 ADP-核糖基化蛋白可以被不同的 ADP-核糖基化特异性阅读器充分识别。这种分子是第一个具有多种活性的核糖基化 NAD,可作用于不同的 ADP-核糖基转移酶,并为开发新的 ADP-核糖基化探针提供了思路。
