The present invention relates to a cellular transport system for bringing a sulfonic acid construct which carries a cargo into a cell and releasing the cargo in the cell's cytoplasm, the cellular transport system comprising: (i) a sulfonate transporter located in the cytoplasm membrane of the cell wherein said sulfonate transporter is capable of transporting said sulfonic acid construct across the cytoplasm membrane into the cytoplasm; (ii) a γ-glutamyl transferase (GGT; EC 2.3.2.2) which is modified to be located in the cytoplasm of the cell, wherein said γ-glutamyl transferase is capable of hydrolyzing said sulfonic acid construct so as to release the cargo. Moreover, the present invention relates to the use of a cellular transport system for bringing a sulfonic acid construct which contains a cargo into a cell and releasing the cargo in the cell's cytoplasm. Further, the present invention relates to a γ-glutamyl transferase for hydrolyzing a sulfonic acid construct which contains a cargo.
本发明涉及一种细胞运输系统,用于将携带货物的磺酸构造体带入细胞并在细胞质中释放货物,所述细胞运输系统包括:(i)位于细胞质膜中的磺酸转运蛋白,其中所述磺酸转运蛋白能够将所述磺酸构造体跨越细胞质膜运输至细胞质;(ii)改性为位于细胞质中的γ-谷氨酰转移酶(GGT;EC 2.3.2.2),其中所述γ-谷氨酰转移酶能够水解所述磺酸构造体以释放货物。此外,本发明涉及使用细胞运输系统将携带货物的磺酸构造体带入细胞并在细胞质中释放货物。此外,本发明涉及用于水解携带货物的磺酸构造体的γ-谷氨酰转移酶。
