“益生元和从未出生的蛋白质”问题

The Problem of the "Prebiotic and Never Born Proteins"

Gerald E. Marsh

摘要:

有人认为,我们所知的生命所使用的有限的蛋白质组不可能是达尔文从所有可能的蛋白质中选择出来的。这种概率论有许多隐含的假设,可能是没有根据的。提出了各种考虑,以表明在蛋白质进化过程中需要取样的氨基酸序列的数量远小于论证所假设的数量。

英文摘要:

It has been argued that the limited set of proteins used by life as we know it could not have arisen by the process of Darwinian selection from all possible proteins. This probabilistic argument has a number of implicit assumptions that may not be warranted. A variety of considerations are presented to show that the number of amino-acid sequences that need have been sampled during the evolution of proteins is far smaller than assumed by the argument.
