Caulobacter crescentus accumulated guanosine tetraphosphate in response to nitrogen starvation but not in response to amino acid starvation. Nitrogen starvation also acted specifically to inhibit certain transitions in the C. crescentus life cycle, and guanosine tetraphosphate may act as an intracellular regulator of cell cycle events.
新月柄杆菌在氮饥饿时会积累四磷酸鸟苷,但在氨基酸饥饿时不会。氮饥饿还特异性地抑制新月柄杆菌生命周期中的某些转变,并且四磷酸鸟苷可能作为细胞周期事件的细胞内调节因子发挥作用。
