DE RecName: Full=2-succinyl-5-enolpyruvyl-6-hydroxy-3-cyclohexene-1-carboxylate synthase; DE Short=SEPHCHC synthase; DE EC=2.2.1.9; DE AltName: Full=Menaquinone biosynthesis protein MenD; GN Name=menD; OrderedLocusNames=PFREUD_07490; OS Propionibacterium freudenreichii subsp. shermanii (strain ATCC 9614 / OS CIP 103027 / CIRM-BIA1). OC Bacteria; Actinobacteria; Actinobacteridae; Actinomycetales; OC Propionibacterineae; Propionibacteriaceae; Propionibacterium. OX NCBI_TaxID=754252; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=CIRM-B1AI; RX PubMed=20668525; DOI=10.1371/journal.pone.0011748; RA Falentin H., Deutsch S.M., Jan G., Loux V., Thierry A., Parayre S., RA Maillard M.B., Dherbecourt J., Cousin F.J., Jardin J., Siguier P., RA Couloux A., Barbe V., Vacherie B., Wincker P., Gibrat J.F., RA Gaillardin C., Lortal S.; RT "The complete genome of Propionibacterium freudenreichii CIRM-BIA1, a RT hardy actinobacterium with food and probiotic applications."; RL PLoS ONE 5:E11748-E11748(2010). CC -!- FUNCTION: Catalyzes the thiamine diphosphate-dependent CC decarboxylation of 2-oxoglutarate and the subsequent addition of CC the resulting succinic semialdehyde-thiamine pyrophosphate anion CC to isochorismate to yield 2-succinyl-5-enolpyruvyl-6-hydroxy-3- CC cyclohexene-1-carboxylate (SEPHCHC) (By similarity). CC -!- CATALYTIC ACTIVITY: Isochorismate + 2-oxoglutarate = 5- CC enolpyruvoyl-6-hydroxy-2-succinyl-cyclohex-3-ene-1-carboxylate + CC CO(2). CC -!- COFACTOR: Binds 1 thiamine pyrophosphate per subunit (By CC similarity). CC -!- COFACTOR: Magnesium or manganese (By similarity). CC -!- PATHWAY: Cofactor biosynthesis; menaquinone biosynthesis; CC menaquinone-2 from chorismate: step 2/8. CC -!- SUBUNIT: Homodimer (By similarity). CC -!- SIMILARITY: Belongs to the TPP enzyme family. MenD subfamily.
