Abstract

The levels of the four ribonucleoside triphosphate (ATP, GTP, UTP and CTP) have been determined in Neurospora crassa in three conditions of exponential growth (on glucose, acetate and glycerol) as well as in the course of a shift-up and a shift-down transition of growth between two of them. Although in some cases the pools appear proportional to the rate of synthesis of ribosomal RNA, this seems not to be strictly dependent on the level of the nucleotides.

摘要

已测定了粗糙脉孢菌在三种指数生长条件下（以葡萄糖、乙酸盐和甘油为营养源）以及在其中两种条件之间的生长向上和向下转变过程中四种核糖核苷三磷酸（ATP、GTP、UTP和CTP）的水平。尽管在某些情况下，这些库似乎与核糖体RNA的合成速率成比例，但这似乎并不严格取决于核苷酸的水平。
