General annotation (Comments)
| Function | Involved in the biosynthesis of alanine. Ref.4 |
| Catalytic activity | L-alanine + 2-oxoglutarate = pyruvate + L-glutamate. |
| Cofactor | Pyridoxal phosphate By similarity. |
| Subunit structure | Homodimer. Ref.4 |
| Subcellular location | Cytoplasm By similarity. |
| Induction | Modestly repressed by alanine and leucine via Lrp. Ref.4 |
| Sequence similarities | Belongs to the class-I pyridoxal-phosphate-dependent aminotransferase family. |
| Biophysicochemical properties | Kinetic parameters: KM=0.55 mM for pyruvate (at 37 degrees Celsius and pH 8.5) Ref.4 KM=4.9 mM for alanine (at 37 degrees Celsius and pH 8.5) |
