Protein attributes

Sequence length	283 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Catalyzes the NAD+-dependent oxidation of both quinate and shikimate to 3-dehydroquinate and 3-dehydroshikimate, respectively. Seems to play a key role in the quinate degradation pathway By similarity.
Catalytic activity	Quinate + NAD+ = 3-dehydroquinate + NADH. HAMAP MF_00222 Shikimate + NAD+ = 3-dehydroshikimate + NADH. HAMAP MF_00222
Pathway	Metabolic intermediate biosynthesis; chorismate biosynthesis; chorismate from D-erythrose 4-phosphate and phosphoenolpyruvate: step 4/7. HAMAP MF_00222
Subunit structure	Homodimer By similarity.
Sequence similarities	Belongs to the shikimate dehydrogenase family.
