Aminoacyl-tRNA synthetase is responsible for covalently linking amino acids to the 3'-end of the cognate tRNA. Peptidyltransferase is responsible for catalyzing the formation of peptide bonds between amino acids during protein synthesis. Glutamine synthetase is responsible for catalyzing the formation of glutamine from ammonia and glutamate. RNA polymerase is responsible for catalyzing the synthesis of RNA from a DNA template. ATP synthase is responsible for synthesizing ATP from ADP and inorganic phosphate.
