Accepted name: 3-dehydroquinate dehydratase
Reaction: 3-dehydroquinate = 3-dehydroshikimate + H2O
For diagram of shikimate and chorismate biosynthesis, click here and for mechanism of reaction, click here
Glossary: quinate = (1R,3R,4R,5R)-1,3,4,5-tetrahydroxycyclohexanecarboxylic acid and is a cyclitol carboxylate
The numbering system used for the 3-dehydroquinate is that of the recommendations on cyclitols, sections I-8 and I-9: and is shown in the reaction diagram). The use of the term ’5-dehydroquinate’ for this compound is based on an earlier system of numbering.
