Function
function
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).
Catalytic activity
- isochorismate + 2-oxoglutarate + H+ = 5-enolpyruvoyl-6-hydroxy-2-succinyl-cyclohex-3-ene-1-carboxylate + CO2
Cofactor
Protein has several cofactor binding sites:
Mn2+ (UniProtKB | Rhea| CHEBI:29035 )
Note: Binds 1 thiamine pyrophosphate per subunit.
Pathway
Quinol/quinone metabolism; 1,4-dihydroxy-2-naphthoate biosynthesis; 1,4-dihydroxy-2-naphthoate from chorismate: step 2/7.
Quinol/quinone metabolism; menaquinone biosynthesis.
