摘要:
The present invention is directed to a method to diversify the chemical composition of proteins produced in vivo comprising the step of disabling, particularly by mutagenesis, the editing function of one of its aminoacyl tRNA synthetases. The present invention is also directed to nucleic acid sequences encoding such mutated aminoacyl tRNA synthetases having their editing site mutated and capable of mischarging its cognate tRNA with a noncanonical amino acid. Also described herein is an improved method for obtaining transformed cells capable of synthetizing in vivo proteins comprising at least a noncanonical amino acid and their use for the production of such proteins.

摘要:
A method of suppressing angiogenesis in a mammal (e.g., for treating tumors, tumor metastasis or a condition that would benefit from decreased angiogenesis) comprises the step of administering to the mammal an angiostatically effective amount of a pharmaceutical composition comprising an isolated antiangiogenic truncated tryptophanyl-tRNA synthetase (TrpRS) polypeptide or an isolated nucleic acid that comprises a polynucleotide sequence that encodes the truncated TrpRS polypeptide. The truncated TrpRS polypeptide comprises residues 71-471 of SEQ ID NO: 10, residues 48-471 of SEQ ID NO: 10, or a polypeptide of approximately 47 kD molecular weight produced by cleavage of the polypeptide of SEQ ID NO: 10 with polymorphonuclear leucocyte elastase.
