Abstract

Nucleotide pools were measured in growing and amino acid-starved Saccharomyces cerevisiae. During amino acid starvation there are neither significant changes in the endogeneous nucleoside triphosphate pool levels nor measurable synthesis of guanosine 5'-diphosphate, 3'-diphosphate. Stable ribonucleic acid synthesis does not appear to be regulated by changes in the triphosphate pools or by the unusual nucleotide guanosine 5'-diphosphate, 3'-diphosphate.

摘要

在生长中的和氨基酸饥饿的酿酒酵母中测量了核苷酸库。在氨基酸饥饿期间,内源性核苷三磷酸库水平没有显著变化,也没有可测量的5'-二磷酸鸟苷-3'-二磷酸的合成。稳定核糖核酸的合成似乎不受三磷酸库变化或异常核苷酸5'-二磷酸鸟苷-3'-二磷酸的调节。
