General annotation (Comments)
| Function | Catalyzes the reversible conversion of 3-phosphohydroxypyruvate to phosphoserine and of 3-hydroxy-2-oxo-4-phosphonooxybutanoate to phosphohydroxythreonine By similarity. |
| Catalytic activity | O-phospho-L-serine + 2-oxoglutarate = 3-phosphonooxypyruvate + L-glutamate. 4-phosphonooxy-L-threonine + 2-oxoglutarate = (3R)-3-hydroxy-2-oxo-4-phosphonooxybutanoate + L-glutamate. |
| Cofactor | Binds 1 pyridoxal phosphate per subunit By similarity. |
| Pathway | Amino-acid biosynthesis; L-serine biosynthesis; L-serine from 3-phospho-D-glycerate: step 2/3. |
| Subunit structure | Homodimer By similarity. |
| Subcellular location | |
| Sequence similarities | Belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family. SerC subfamily. |
