This enzyme belongs to the family of ligases, to be specific, those forming carbon-oxygen bonds in aminoacyl-tRNA and related compounds. The systematic name of this enzyme class is L-lysine:tRNALys ligase (AMP-forming). Other names in common use include lysyl-tRNA synthetase, lysyl-transfer ribonucleate synthetase, lysyl-transfer RNA synthetase, L-lysine-transfer RNA ligase, lysine-tRNA synthetase, and lysine translase.
