Protein

2-succinyl-5-enolpyruvyl-6-hydroxy-3-cyclohexene-1-carboxylate synthase

Gene

menD

Organism
Escherichia coli (strain ATCC 8739 / DSM 1576 / Crooks)
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

Catalyzes the thiamine diphosphate-dependent decarboxylation of 2-oxoglutarate and the subsequent addition of the resulting succinic semialdehyde-thiamine pyrophosphate anion to isochorismate to yield 2-succinyl-5-enolpyruvyl-6-hydroxy-3-cyclohexene-1-carboxylate (SEPHCHC).UniRule annotation

Catalytic activityi

Isochorismate + 2-oxoglutarate = 5-enolpyruvoyl-6-hydroxy-2-succinyl-cyclohex-3-ene-1-carboxylate + CO2.UniRule annotation

Cofactori

Magnesium or manganese.UniRule annotation
Binds 1 thiamine pyrophosphate per subunit.UniRule annotation
