Isolated soybean (Glycine max L. cv. Kent) embyronic axes metabolized [(14)C]glycine to ATP within the 1 hour of imbibition. Radioactivity was not detected in GTP until the 3rd hour. Throughout most of the first 24 hours of germination about 10 to 26 times as much label from [(14)C]glycine appears in ATP as GTP. About five times as much [(14)C]hypoxanthine and [(14)C]inosine was converted into GTP as into ATP in embryonic axes. Two independent pools of IMP appear to be used in purine nucleotide synthesis of soybean axes.
在吸胀的 1 小时内，分离的大豆（Glycine max L. cv. Kent）胚胎轴将 [(14)C]甘氨酸代谢为 ATP。直到第 3 小时才检测到 GTP 中的放射性。在发芽的前 24 小时的大部分时间里，来自 [(14)C]甘氨酸的标记物在 ATP 中的出现量大约是 GTP 的 10 到 26 倍。在胚胎轴中，大约有 [(14)C]次黄嘌呤和 [(14)C]肌苷转化为 GTP 的量是转化为 ATP 的 5 倍。在大豆轴的嘌呤核苷酸合成中，似乎有两个独立的 IMP 池被利用。
