Experiments on model peptides show that the rate of deamidation of asparaginyl residues depends strongly on the nature of neighboring residues. The natural distribution of glutaminyl and asparaginyl residues is ordered with respect to the biological lifetime of the peptides and the functional groups of the residues neighboring to glutaminyl and asparaginyl residues. The rates of deamidation of such amide peptides under physiological conditions could serve as useful timers of development and aging.
对模型肽的实验表明,天冬酰胺残基的脱酰胺速率强烈依赖于相邻残基的性质。谷氨酰胺残基和天冬酰胺残基的自然分布在肽的生物寿命以及与谷氨酰胺和天冬酰胺残基相邻的残基官能团方面是有序的。此类酰胺肽在生理条件下的脱酰胺速率可作为发育和衰老的有用计时指标。
