Following the observation of lysine for arginine misincorporation at the poor choice codon arg-AGA, a comparison of codon usage patterns for highly expressed mRNA's in E. coli provides a basis for the proposal that the major codon preference is subject to mistranslational constraints. In addition, the codons are utilized, as well as arranged, to provide a hydropathically conservative amino acid as the most probable replacement resulting from a mistranslational event.
在观察到赖氨酸在较差选择密码子精氨酸-AGA处误掺入精氨酸后,对大肠杆菌中高表达mRNA的密码子使用模式进行比较,为以下提议提供了依据:主要密码子偏好受到错译限制。此外,密码子的使用和排列方式,是为了提供一种亲水性保守氨基酸,作为错译事件最可能产生的替代物。
