case <OC:Archaea>
FUNCTIONCatalyzes the oxidative deamination and cyclization of 2- amino-3,7-dideoxy-D-threo-hept-6-ulosonic acid (ADH) to yield 3- dehydroquinate (DHQ), which is fed into the canonical shikimic pathway of aromatic amino acid biosynthesis.
CATALYTIC ACTIVITY Reaction=2-amino-2,3,7-trideoxy-D-lyxo-hept-6-ulosonate + H2O + NAD(+) = 3-dehydroquinate + H(+) + NADH + NH4(+); Xref=Rhea:RHEA:25956, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:28938, ChEBI:CHEBI:32364, ChEBI:CHEBI:57540, ChEBI:CHEBI:57945, ChEBI:CHEBI:58859; EC=1.4.1.24;
end case
SIMILARITYBelongs to the archaeal-type DHQ synthase family.
