Details:

Aminoacyl-trna synthetases catalyze the aminoacylation of trna by their cognate amino acid. Because of their central role in linking amino acids with nucleotide triplets contained in trnas, aminoacyl-trna synthetases are thought to be among the first proteins that appeared in evolution. Tyrosyl-trna synthetase belongs to the class i trna synthetase family. Cytokine activities have also been observed for the human tyrosyl-trna synthetase, after it is split into two parts, an n-terminal fragment that harbors the catalytic site and a c-terminal fragment found only in the mammalian enzyme. The n-terminal fragment is an interleukin-8-like cytokine, whereas the released c-terminal fragment is an emap ii-like cytokine. [Provided by refseq
