The biosynthesis of glutathione starts with the introduction of L-glutamic acid through either a glutamate:sodium symporter, glutamate / aspartate : H+ symporter GltP or a
glutamate / aspartate ABC transporter. Once in the cytoplasm, L-glutamice acid reacts with L-cysteine through an ATP glutamate-cysteine ligase resulting in gamma-glutamylcysteine. This compound reacts which Glycine through an ATP driven glutathione synthetase thus catabolizing Glutathione.
This compound is metabolized through a spontaneous reaction with an oxidized glutaredoxin resulting in a reduced glutaredoxin and an oxidized glutathione. This compound is reduced by a NADPH glutathione reductase resulting in a glutathione.
Glutathione can then be degraded into various different glutathione containg compounds by reacting with a napthalene through a glutathione S-transferase
