LITERATURE
truncated enzyme lacking 70 amino acid residues in the N-terminus, overexpression in Escherichia coli

-
expression of wild-type and mutant enzymes in yeast YBC-603 cells, functional overexpression of GST- and His6-tagged enzyme in Escherichia coli strain Top10. Expression in yeast cells at low copy number, since overexpression is cytotoxic, while moderate AspRS accumulation in the cell is not deleterious

expression of wild-type enzyme, amino acid residues 1-557, and a truncated mutant enzyme, amino acid resdiues 71-557, as His-tagged proteins in Escherichia coli
