| FUNCTION | Catalyzes the cleavage of 2-amino-3-ketobutyrate to glycine and acetyl-CoA. |
| CATALYTIC ACTIVITY | Reaction=glycine + acetyl-CoA = (2S)-2-amino-3-oxobutanoate + CoA; Xref=Rhea:RHEA:20736, ChEBI:CHEBI:57287, ChEBI:CHEBI:57288, ChEBI:CHEBI:57305, ChEBI:CHEBI:78948; EC=2.3.1.29; |
| COFACTOR | Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326; Note=Binds 1 pyridoxal phosphate per subunit.; |
| PATHWAY | Amino-acid degradation; L-threonine degradation via oxydo- reductase pathway; glycine from L-threonine: step 2/2. |
| SUBUNIT | Homodimer. |
| SIMILARITY | Belongs to the class-II pyridoxal-phosphate-dependent aminotransferase family. |
