RT "Complete sequence of chromosome of Methanococcus maripaludis C5.";
RL Submitted (MAR-2007) to the EMBL/GenBank/DDBJ databases.
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:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:28938,
CC ChEBI:CHEBI:32364, ChEBI:CHEBI:57540, ChEBI:CHEBI:57945,
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}.
