Function[MEND_ECOLI] 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).[1] [2] Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedMenD (2-succinyl-5-enolpyruvyl-6-hydroxy-3-cyclohexadiene-1-carboxylate) synthase belongs to the superfamily of thiamin diphosphate-dependent decarboxylases, which converts isochorismate and 2-oxoglutarate to SHCHC, pyruvate, and carbon dioxide. Here, we report the first crystal structure of apo-MenD from Escherichia coli determined in tetragonal crystal form. The subunit displays the typical three-domain structure observed for ThDP-dependent enzymes. Analytical gel filtration shows that EcMenD behaves as a dimer as well as a tetramer. Circular dichroism and isothermal calorimetry results confirm EcMenD dependency on ThDP, which concomitantly helps to stabilize with better configuration. Structural insights of the MenD from Escherichia coli reveal ThDP affinity.,Priyadarshi A, Saleem Y, Nam KH, Kim KS, Park SY, Kim EE, Hwang KY Biochem Biophys Res Commun. 2009 Mar 20;380(4):797-801.
