Protein
4-hydroxythreonine-4-phosphate dehydrogenase
Gene
pdxA, aq_852
Organism
Aquifex aeolicus (strain VF5)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

Catalyzes the NAD(P)-dependent oxidation of 4-(phosphohydroxy)-L-threonine (HTP) into 2-amino-3-oxo-4-(phosphohydroxy)butyric acid which spontaneously decarboxylates to form 3-amino-2-oxopropyl phosphate (AHAP) By similarity.UniRule annotation

Catalytic activityi

4-phosphonooxy-L-threonine + NAD+ = 3-amino-2-oxopropyl phosphate + CO2 + NADH.UniRule annotation

Cofactori

Binds 1 divalent metal cation per subunit By similarity.
