Comments [?]

Function Catalyzes the cleavage of 2-amino-3-ketobutyrate to glycine and acetyl-CoA.
Catalytic activity RHEA:20736: acetyl-CoA + glycine = (2S)-2-amino-3-oxobutanoate + CoA
EC 2.3.1.29
Cofactor pyridoxal 5'-phosphate
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.

Keywords [?]
