Amino acid-starved cells of Escherichia coli relA+, which contain a large number of glycogen particles, are able to survive in phosphate buffer for a longer time period than their relaxed counterparts. With regard to NH4+ starvation differences in the survival of both strains were not found. NH4+ starved cells of E. coli relA are able to synthesize glycogen but amino acid-starved cells of the relA strain are not. We suggest that the synthesis of glycogen triggered by guanosine tetraphosphate during amino acid starvation is responsible for the prolonged viability of the E. coli relA+ strain.
含有大量糖原颗粒的大肠杆菌relA +氨基酸饥饿细胞，比其松弛型对应细胞能够在磷酸盐缓冲液中存活更长时间。关于NH4 +饥饿，未发现两种菌株在存活方面存在差异。大肠杆菌relA的NH4 +饥饿细胞能够合成糖原，但relA菌株的氨基酸饥饿细胞则不能。我们认为，氨基酸饥饿期间由四磷酸鸟苷引发的糖原合成是大肠杆菌relA +菌株延长生存能力的原因。
