General annotation (Comments)
| Function | 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. HAMAP-Rule MF_00536 |
| Catalytic activity | 4-phosphonooxy-L-threonine + NAD+ = 3-amino-2-oxopropyl phosphate + CO2 + NADH. HAMAP-Rule MF_00536 |
| Cofactor | Binds 1 divalent metal cation per subunit. Can use ions such as zinc, magnesium or cobalt By similarity. |
| Pathway | Cofactor biosynthesis; pyridoxine 5'-phosphate biosynthesis; pyridoxine 5'-phosphate from D-erythrose 4-phosphate: step 4/5. HAMAP-Rule MF_00536 |
| Subunit structure | Homodimer By similarity. |
| Subcellular location | Cytoplasm By similarity. |
| Miscellaneous | The active site is located at the dimer interface By similarity. HAMAP-Rule MF_00536 |
| Sequence similarities | Belongs to the PdxA family. |
