Aminoacyl tRNA synthetases Definition

  • Correct matching up of tRNA and amino acid is carried out by a family of related enzymes called aminoacyl-tRNA synthetases.

Aminoacyl tRNA synthetases Explanation

An aminoacyl-tRNA synthetase, also called tRNA-ligase, is an enzyme that attaches the appropriate amino acid onto its tRNA. It does so by catalyzing the esterification of a specific cognate amino acid or its precursor to one of all its compatible cognate tRNAs to form an aminoacyl-tRNA. In humans, the 20 different types of aa-tRNA are made by the 20 different aminoacyl-tRNA synthetases, one for each amino acid of the genetic code.
