Chains	Enzyme Name	Description	Catalytic Residues
A	tyrosine-tRNA ligase M-CSA #197	Tyrosine-tRNA ligases (TyrRS; also known as Tyrosyl-tRNA synthetases, EC:6.1.1.1) are widely distributed, being found in archaea, bacteria and eukaryotes. TyrRS is a homodimer which attaches Tyr to the appropriate tRNA. TyrRS is a class I tRNA synthetases, so it aminoacylates the 2'-OH of the nucleotide at the 3' end of the tRNA.
