Comments [?]

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) (By similarity).
Catalytic activity Isochorismate + 2-oxoglutarate = 5-enolpyruvoyl-6-hydroxy-2-succinyl-cyclohex-3-ene-1-carboxylate + CO(2).
Cofactor Magnesium or manganese (By similarity).
Binds 1 thiamine pyrophosphate per subunit (By similarity).
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.
Subunit Homodimer (By similarity).
Similarity Belongs to the TPP enzyme family. MenD subfamily.
