Pathway Description
tRNA Charging
Escherichia coli
Metabolic Pathway
This pathway is a compilation of Escherichia coli tRNA charging reactions involving amino acids transported into the cell. The aminoacyl-tRNA synthetase is an enzyme that attaches the appropriate amino acid onto its tRNA 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, which plays an important role in RNA translation. 20 different Aminoacyl-tRNA synthetases can make 20 different types of aa-tRNA for each amino acid according to the genetic code. This process is called "charging" or "loading" the tRNA with amino acid. Ribosome can transfer the amino acid from tRNA to a growing peptide after the tRNA is charged.
