RC STRAIN=JCM 14624 {ECO:0000313|EMBL:ELZ08231.1, RC ECO:0000313|Proteomes:UP000011560}; RX PubMed=25393412; DOI=10.1371/journal.pgen.1004784; RA Becker E.A., Seitzer P.M., Tritt A., Larsen D., Krusor M., Yao A.I., Wu D., RA Madern D., Eisen J.A., Darling A.E., Facciotti M.T.; RT "Phylogenetically driven sequencing of extremely halophilic archaea reveals RT strategies for static and dynamic osmo-response."; RL PLoS Genet. 10:E1004784-E1004784(2014). CC -!- FUNCTION: Involved in the third step of the chorismate pathway, which CC leads to the biosynthesis of aromatic amino acids. Catalyzes the cis- CC dehydration of 3-dehydroquinate (DHQ) and introduces the first double CC bond of the aromatic ring to yield 3-dehydroshikimate. CC {ECO:0000256|HAMAP-Rule:MF_00214}. CC -!- CATALYTIC ACTIVITY: CC Reaction=3-dehydroquinate = 3-dehydroshikimate + H2O; CC Xref=Rhea:RHEA:21096, ChEBI:CHEBI:15377, ChEBI:CHEBI:16630, CC ChEBI:CHEBI:32364; EC=4.2.1.10; CC Evidence={ECO:0000256|ARBA:ARBA00001864, ECO:0000256|HAMAP- CC Rule:MF_00214}; CC -!- PATHWAY: Metabolic intermediate biosynthesis; chorismate biosynthesis; CC chorismate from D-erythrose 4-phosphate and phosphoenolpyruvate: step CC 3/7. {ECO:0000256|HAMAP-Rule:MF_00214}. CC -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_00214}. CC -!- SIMILARITY: Belongs to the type-I 3-dehydroquinase family. CC {ECO:0000256|HAMAP-Rule:MF_00214}. CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_00214}. CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ CC whole genome shotgun (WGS) entry which is preliminary data. CC {ECO:0000313|EMBL:ELZ08231.1}.
