Protein

4-hydroxythreonine-4-phosphate dehydrogenase

Gene

pdxA

Organism
Colwellia psychrerythraea (strain 34H / ATCC BAA-681) (Vibrio psychroerythus)
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).UniRule annotation

Catalytic activityi

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

Cofactori

Zn2+UniRule annotation, Mg2+UniRule annotation, Co2+UniRule annotationNote: Binds 1 divalent metal cation per subunit. Can use ions such as Zn(2+), Mg(2+) or Co(2+).UniRule annotation
