Talking bacteria: The combination of NMR spectroscopy and 4,5‐dihydroxy‐2,3‐pentanedione (DPD) homologue analysis reveals that DPD, a bacterial signaling compound in the autoinducer‐2 (AI‐2) class (see scheme), exists as a much more complex structural array of molecules than previously appreciated. This finding suggests the existence of a larger bacterial chemical signaling language than previously thought
会说话的细菌:核磁共振波谱和 4,5-二羟基-2,3-戊二酮 (DPD) 同源物分析的组合表明 DPD,一种自诱导剂-2 (AI-2) 类(见方案)中的细菌信号化合物,存在作为比以前理解的要复杂得多的分子结构阵列。这一发现表明存在比以前认为的更大的细菌化学信号语言。
