It contains the characteristic class I HIGH and KMSKS motifs, which are involved in ATP binding. Cysteine-tRNA ligase (also known as cysteinyl-tRNA synthetase) (6.1.1.16) is an alpha monomer and belongs to class Ia [1]. It aminoacylates the 2'-OH of the nucleotide at the 3' of the appropriate tRNA. It is highly specific despite not possessing the amino acid editing activity characteristic of many other tRNA ligases [2][4].
