Protein

4-hydroxythreonine-4-phosphate dehydrogenase

Gene

pdxA

Organism
Salmonella typhi
Status
Reviewed-Annotation score: -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

Miscellaneous

The active site is located at the dimer interface.UniRule annotation

Catalytic activityi

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

Cofactori

Zn2+UniRule annotation, Mg2+UniRule annotation, Co2+UniRule annotationNote: Binds 1 divalent metal cation per subunit. Can use ions such as Zn2+, Mg2+ or Co2+.UniRule annotation

Pathwayi: pyridoxine 5'-phosphate biosynthesis

This protein is involved in step 4 of the subpathway that synthesizes pyridoxine 5'-phosphate from D-erythrose 4-phosphate.UniRule annotation
Proteins known to be involved in the 5 steps of the subpathway in this organism are:
  1. D-erythrose-4-phosphate dehydrogenase (epd)
  2. Erythronate-4-phosphate dehydrogenase (pdxB)
  3. Phosphoserine aminotransferase (serC)
  4. 4-hydroxythreonine-4-phosphate dehydrogenase (pdxA)
  5. Pyridoxine 5'-phosphate synthase (pdxJ)
This subpathway is part of the pathway pyridoxine 5'-phosphate biosynthesis, which is itself part of Cofactor biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes pyridoxine 5'-phosphate from D-erythrose 4-phosphate, the pathway pyridoxine 5'-phosphate biosynthesis and in Cofactor biosynthesis.
