The shikimate pathway (shikimic acid pathway) is a seven-step metabolic pathway used by bacteria, archaea, fungi, algae, some protozoans, and plants for the biosynthesis of folates and aromatic amino acids (tryptophan, phenylalanine, and tyrosine). This pathway is not found in mammals.
The shikimate pathway, named after shikimic acid as important intermediate, is a seven-step metabolic route used by bacteria, fungi, algae, parasites, and plants for the biosynthesis of aromatic amino acids (phenylalanine, tyrosine, and tryptophan).
3-Dehydroquinate Dehydratase is an enzyme that catalyzes the third step of the shikimate pathway. The shikimate pathway is a biosynthetic pathway that allows plants, fungi, and bacteria to produce aromatic amino acids. [2] Mammals do not have this pathway, meaning that they must obtain these essential amino acids through their diet.
3-Deoxy-D-arabinoheptulosonate 7-phosphate (DAHP) synthase (EC 2.5.1.54) is the first enzyme in a series of metabolic reactions known as the shikimate pathway, which is responsible for the biosynthesis of the amino acids phenylalanine, tyrosine, and tryptophan. Since it is the first enzyme in the shikimate pathway, it controls the amount of ...
Shikimate kinase (EC 2.7.1.71) is an enzyme that catalyzes the ATP-dependent phosphorylation of shikimate to form shikimate 3-phosphate. [1] This reaction is the fifth step of the shikimate pathway, [ 2 ] which is used by plants and bacteria to synthesize the common precursor of aromatic amino acids and secondary metabolites.
The shikimate pathway is a target for herbicides and other non-toxic drugs because the shikimate pathway is not present in humans. Glyphosate, a commonly used herbicide, is an inhibitor of 5-enolpyruvylshikimate 3-phosphate synthase or EPSP synthase, an enzyme in the shikimate pathway. The problem is that this herbicide has been utilized for ...
In enzymology, a shikimate O-hydroxycinnamoyltransferase (EC 2.3.1.133) is an enzyme that catalyzes the chemical reaction. 4-coumaroyl-CoA + shikimate CoA + 4-coumaroylshikimate. Thus, the two substrates of this enzyme are 4-coumaroyl-CoA and shikimate, whereas its two products are CoA and 4-coumaroylshikimate.
Chorismate synthase catalyzes the last of the seven steps in the shikimate pathway which is used in prokaryotes, fungi and plants for the biosynthesis of aromatic amino acids. It catalyzes the 1,4-trans elimination of the phosphate group from 5-enolpyruvylshikimate-3-phosphate (EPSP) to form chorismate which can then be used in phenylalanine ...
