Protein attributes

Sequence length	148 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Catalytic activity	3-dehydroquinate = 3-dehydroshikimate + H2O. HAMAP-Rule MF_00169
Pathway	Metabolic intermediate biosynthesis; chorismate biosynthesis; chorismate from D-erythrose 4-phosphate and phosphoenolpyruvate: step 3/7. HAMAP-Rule MF_00169
Subunit structure	Homododecamer. Ref.3
Sequence similarities	Belongs to the type-II 3-dehydroquinase family.
Caution	Phe-23 is present instead of the conserved Tyr which is expected to be an active site residue.
