Abstract
Pyrophosphate (PPi) content of Escherichia coli is increased manyfold when the growth of the cells is limited by inhibition of the synthesis of nucleotides. The accumulated PPi is immediately degraded when inhibition is released and growth allowed to resume. Other tested nutritional deficiencies (starvation of carbon source, sulfate or an amino acid) fail to induce PPi accumulation.
摘要
当大肠杆菌细胞的生长因核苷酸合成受到抑制而受到限制时，其焦磷酸（PPi）含量会增加许多倍。当抑制解除并恢复生长时，积累的PPi会立即降解。其他经测试的营养缺陷（碳源、硫酸盐或氨基酸饥饿）均未能诱导PPi积累。
