Type: | Family | Name: | Cysteinyl-tRNA synthetase/mycothiol ligase |
Description: | This entry represents a subgroup of the class-I aminoacyl-tRNA synthetase family. It includes cysteinyl-tRNA synthetase and the related enzyme mycothiol ligase [].Cysteine-tRNA ligase (also known as Cysteinyl-tRNA synthetase) () is an alpha monomer and belongs to class Ia []. It is highly specific despite not possessing the amino acid editing activity characteristic of many other tRNA ligases [].Mycothiol ligase, also known as L-cysteine:1D-myo-inositol 2-amino-2-deoxy-alpha-D-glucopyranoside ligase, uses ATP to ligate a Cys residue to a mycothiol precursor molecule, in the second to last step in mycothiol biosynthesis []. | Short Name: | Cys-tRNA/MSH_ligase |
