Recent experiments on the deamidation of glutaminyl and asparaginyl residues in peptides and proteins support the hypothesis that these residues may serve as molecular clocks that control biological processes. A hypothesis is now offered that suggests that these molecular clocks are set by rejection or accumulation of appropriate sequences of residues including a glutaminyl or asparaginyl residue during evolution.
最近对肽和蛋白质中谷氨酰胺残基和天冬酰胺残基脱酰胺作用的实验支持了这样一种假说,即这些残基可能充当控制生物过程的分子时钟。现在提出一种假说,认为这些分子时钟是在进化过程中通过包含谷氨酰胺残基或天冬酰胺残基的适当残基序列的排斥或积累而设定的。
