A metabolic system composed of nucleic acid enzymes is proposed to have existed prior to the evolution of ribosomal protein synthesis. Vestiges of these nucleic acid enzymes persist in contemporary coenzymes. This proposal rationalizes the fact that many coenzymes are nucleotides or heterocyclic bases which could be derived from nucleotides.
一种由核酸酶组成的代谢系统被认为在核糖体蛋白质合成进化之前就已存在。这些核酸酶的遗迹存在于当代辅酶中。这一观点解释了许多辅酶是核苷酸或可从核苷酸衍生而来的杂环碱这一事实。
