Embodiments of the present disclosure describe non-canonical amino acids characterized by the formula A—L—B, where A is an amino acid, L is a linker, and B is a biotin or a biotin-analog group. Embodiments describe translation systems comprising an orthogonal tRNA; an orthogonal aminoacyl-tRNA-synthetase, and a non- canonical amino acid with a biotin-containing side-chain or biotin-analog-containing side-chain; wherein the O-RS preferentially aminoacylates the O-tRNA with the non- canonical amino acid; wherein the non-canonical amino acid is incorporated into a protein at a specific site during translation
本公开描述的实施例描述了由公式A—L—B表征的非规范氨基酸,其中A是氨基酸,L是连接剂,B是生物素或生物素类似物基团。实施例描述了包括一个正交tRNA、一个正交氨基酰-tRNA合成酶和一个具有生物素侧链或生物素类似物侧链的非规范氨基酸的翻译系统;其中O-RS优先使用非规范氨基酸氨酰化O-tRNA;其中非规范氨基酸在翻译过程中被特定地插入到蛋白质的一个位点。
