<p><b>New page</b></p><div>However, not all peptide bonds are formed in this way. In a few cases, peptides are synthesized by specific enzymes. For example, the tripeptide [[glutathione]] is an essential part of the defenses of cells against oxidative stress. This peptide is synthesized in two steps from free amino acids. In the first step, [[gamma-glutamylcysteine synthetase]] condenses cysteine and [[glutamate]] through a peptide bond formed between the side chain carboxyl of the glutamate (the gamma carbon of this side chain) and the amino group of the cysteine. This dipeptide is then condensed with glycine by [[glutathione synthetase]] to form glutathione.</div>FuzzyBot
