3-dehydroquinate synthase II (EC 1.4.1.24, DHQ synthase II, MJ1249 (gene), aroB' (gene)) is an enzyme with systematic name 2-amino-3,7-dideoxy-D-threo-hept-6-ulosonate:NAD+ oxidoreductase (deaminating).[1] This enzyme catalyses the following chemical reaction
- 2-amino-3,7-dideoxy-D-threo-hept-6-ulosonate + H2O + NAD+ 3-dehydroquinate + NH3 + NADH + H+
The enzyme was isolated from the archaeon Methanocaldococcus jannaschii.
