Tyrosyl-tRNA Synthetase, Recombinant, Human, aa1-528, His-tag (YARS, CMTDIC, TYRRS, YRS, YTS)

Tyrosyl-tRNA synthetase, also known as YARS, belongs to the class I tRNA synthetase family. YARS is essential enzyme that catalyze the aminoacylation of tRNATrp with tryptophan, an essential function of the cell's protein synthesis machinery. Expression of YARS is highly stimulated in human cells by the addition of IFN-gamma. Source: Recombinant corresponding to aa1-528 from human YARS, fused to His-tag at N-terminus expressed in E.coli.
