CC   -!- FUNCTION: Catalyzes the oxidative deamination and cyclization of 2-
CC       amino-3,7-dideoxy-D-threo-hept-6-ulosonic acid (ADH) to yield 3-
CC       dehydroquinate (DHQ), which is fed into the canonical shikimic pathway
CC       of aromatic amino acid biosynthesis. {ECO:0000255|HAMAP-Rule:MF_01244}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2-amino-2,3,7-trideoxy-D-lyxo-hept-6-ulosonate + H2O + NAD(+)
CC         = 3-dehydroquinate + H(+) + NADH + NH4(+); Xref=Rhea:RHEA:25956,

CC         ChEBI:CHEBI:58859; EC=1.4.1.24; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_01244};
CC   -!- SIMILARITY: Belongs to the archaeal-type DHQ synthase family.
CC       {ECO:0000255|HAMAP-Rule:MF_01244}.
