NameShikimic acid
SpeciesSaccharomyces cerevisiae
StrainBaker's yeast
DescriptionShikimic acid is an intermediate in the chorismate biosynthesis pathway also called shikimate pathway. This pathway occurs in plants and microorganisms. Chorismate is an important intermediate that leads to the biosynthesis of several essential metabolites, including the aromatic amino acids L-phenylalanine, L-tyrosine and L-tryptophan, vitamins E and K, ubiquinone and certain siderophore.
