GENETICALLY ENCODED TYROSINE SULFATION OF PROTEINS IN EUKARYOTES

摘要

An engineered tyrosyl-tRNA synthetase/tRNA pair that co-translationally incorporates O-sulfotyrosine in response to UAG codons in E. coli and mammalian cells is described herein. This platform enables recombinant expression of eukaryotic proteins homogeneously sulfated at chosen sites.
