>cd00674 LysRS_core_class_I This is the catalytic core domain of lysyl tRNA synthetase (LysRS). This class I enzyme is a monomer, which aminoacylates the 2'-OH of the nucleotide at the 3' of the appropriate tRNA. The core domain is based on the Rossman fold and is responsible for the ATP-dependent formation of the enzyme bound aminoacyl-adenylate. It contains the characteristic class I HIGH and KMSKS motifs, which are involved in ATP binding. The class I LysRS is found only in archaea and some bacteria and has evolved separately from class II LysRS, as the two do not share structural or sequence similarity.
