Effect of Physiological Changes in Cystathionase Activity on Amino Acid and Glutathione Metabolism in Rat Fetus

  • Chapter
Endocrine and Biochemical Development of the Fetus and Neonate

Abstract

The trans-sulphuration pathway serves to synthesize cysteine from methionine. This pathway is important to ensure an adequate supply of cysteine and, indeed, if the flux through the pathway is decreased, cysteine becomes an essential amino acid. A key enzyme of the pathway is cystathionase, which catalyzes the cleavage of cystathionine to yield cysteine.
