Biosynthesis: The enzyme 3-dehydroquinate dehydratase uses 3-dehydroquinate to produce 3-dehydroshikimate and H 2 O. 3-Dehydroshikimate is then reduced to shikimic acid by the enzyme shikimate dehydrogenase, which uses nicotinamide adenine dinucleotide phosphate (NADPH) as a cofactor. Biosynthesis of shikimic acid from 3-dehydroquinate
In enzymology, a shikimate dehydrogenase (EC 1.1.1.25) is an enzyme that catalyzes the chemical reaction shikimate + NADP + ⇌ {\displaystyle \rightleftharpoons } 3-dehydroshikimate + NADPH + H + Thus, the two substrates of this enzyme are shikimate and NADP + , whereas its 3 products are 3-dehydroshikimate , NADPH , and H + .
The enzyme 3-dehydroquinate dehydratase (EC 4.2.1.10) catalyzes the chemical reaction. 3-dehydroquinate 3-dehydroshikimate + H 2 O. This enzyme belongs to the family of lyases, specifically the hydro-lyases, which cleave carbon-oxygen bonds. This enzyme participates in phenylalanine, tyrosine and tryptophan biosynthesis
3-dehydroshikimate dehydratase (EC 4.2.1.118) is an enzyme with systematic name 3-dehydroshikimate hydro-lyase. [1] [2] This enzyme catalyses the following chemical reaction. 3-dehydro-shikimate 3,4-dihydroxybenzoate + H 2 O. This enzyme catalyses an early step in the biosynthesis of petrobactin.
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 figure below). [1] [2] Shikimate 3-phosphate is then coupled with phosphoenol pyruvate to give 5-enolpyruvylshikimate-3-phosphate via the enzyme 5-enolpyruvylshikimate-3-phosphate ...
Shikimic acid can also be extracted from the seeds of the sweetgum (Liquidambar styraciflua) fruit, [2] which is abundant in North America, in yields of around 1.5%. For example, 4 kg (8.8 lb) of sweetgum seeds is needed for fourteen packages of Tamiflu. By comparison, star anise has been reported to yield 3% to 7% shikimic acid.

The episodes of the Tokyo Mew Mew anime series are based on the manga series of the same name written by Reiko Yoshida and illustrated by Mia Ikumi.Directed by Noriyuki Abe and produced by Studio Pierrot, [1] the episodes focus on five girls infused with the DNA of rare animals that gives them special powers and allows them to transform into "Mew Mews".
