Unit Definition

One unit will activate and attach 1.0 picomole (10-12 mole) of labeled amino acid to tRNA in 10 min at pH 7.6 at 37 °C (amino acid used: L-arginine).

Physical form

Solution in 50% glycerol containing 10 mM Tris HCl, pH 7.2, 10 mM MgCl2, 30 mM 2-mercaptoethanol and 10 mM KCl

Application

Aminoacyl tRNA synthetase may be useful in the study of protein synthesis and regulation .

Biochem/physiol Actions

Aminoacyl tRNA synthetase attaches amino acids to their corresponding tRNA, which is essential for protein synthesis. Both classes of aminoacyl tRNA synthetases are multi-domain proteins .
