Enzyme Information
| 4.2.99.20 | 2-succinyl-6-hydroxy-2,4-cyclohexadiene-1-carboxylate synthase. based on mapping to UniProt P37355 5-enolpyruvoyl-6-hydroxy-2-succinylcyclohex-3-ene-1-carboxylate = (1R,6R)-6-hydroxy-2-succinylcyclohexa-2,4-diene-1-carboxylate + pyruvate. -!- Involved in the biosynthesis of vitamin K2 (menaquinone). -!- In most anaerobes and all Gram-positive aerobes, menaquinone is the sole electron transporter in the respiratory chain and is essential for their survival. -!- It had previously been thought that the reactions carried out by this enzyme and EC 2.2.1.9 were carried out by a single enzyme but this has since been disproved. -!- Formerly EC 2.5.1.64 and EC 4.2.99.n1. |
