CC -!- FUNCTION: Catalyzes the cleavage of 2-amino-3-ketobutyrate to glycine
CC and acetyl-CoA. {ECO:0000256|HAMAP-Rule:MF_00985}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=acetyl-CoA + glycine = (2S)-2-amino-3-oxobutanoate + CoA;
CC Xref=Rhea:RHEA:20736, ChEBI:CHEBI:57287, ChEBI:CHEBI:57288,
CC ChEBI:CHEBI:57305, ChEBI:CHEBI:78948; EC=2.3.1.29;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00985};
CC -!- COFACTOR:
CC Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00985};
CC Note=Binds 1 pyridoxal phosphate per subunit. {ECO:0000256|HAMAP-
CC Rule:MF_00985};
CC -!- PATHWAY: Amino-acid degradation; L-threonine degradation via oxydo-
CC reductase pathway; glycine from L-threonine: step 2/2.
CC {ECO:0000256|HAMAP-Rule:MF_00985}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|ARBA:ARBA00011738, ECO:0000256|HAMAP-
CC Rule:MF_00985}.
CC -!- SIMILARITY: Belongs to the class-II pyridoxal-phosphate-dependent
CC aminotransferase family. {ECO:0000256|HAMAP-Rule:MF_00985}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
