Aminoshikimic acid is an unnatural carbohydrate, although aminoshikimic acid is the namesake of the aminoshikimate pathway, which generates the 3-amino-5-hydroxybenzoic acid (AHBA) starter unit required for the biosynthesis of the ansamycins and mitomycins. [1]
Shikimic acid, more commonly known as its anionic form shikimate, is a cyclohexene, a cyclitol and a cyclohexanecarboxylic acid. It is an important biochemical metabolite in plants and microorganisms.
[23] [24] The aromatic amino acid phenylalanine, synthesized in the shikimic acid pathway, is the common precursor of phenol containing amino acids and phenolic compounds. In plants, the phenolic units are esterified or methylated and are submitted to conjugation , which means that the natural phenols are mostly found in the glycoside form ...
The pathway starts with two substrates, phosphoenol pyruvate and erythrose-4-phosphate, and ends with chorismate (chrorismic acid), a substrate for the three aromatic amino acids. The fifth enzyme involved is the shikimate kinase , an enzyme that catalyzes the ATP -dependent phosphorylation of shikimate to form shikimate 3-phosphate (shown in ...

The phenylpropanoids are a diverse family of organic compounds that are biosynthesized by plants from the amino acids phenylalanine and tyrosine in the shikimic acid pathway. [1] Their name is derived from the six-carbon, aromatic phenyl group and the three-carbon propene tail of coumaric acid , which is the central intermediate in ...
[10] [11] [12] An industrial method for the production of shikimic acid using fermentation of E. coli bacteria was discovered in 2005, [13] [14] and applied in the 2009 swine flu pandemic to address Tamiflu shortages, eventually reversing price increases for star anise as a raw material of shikimic acid.

He is one of the eight children of Christiaan Eijkman, the headmaster of a local school, and Johanna Alida Pool. His brother Christiaan Eijkman (1858–1930) was a physician and professor of physiology whose demonstration that beriberi is caused by poor diet led to the discovery of vitamins. Together with Sir Frederick Hopkins, his brother ...
