RT   "The Staphylococcus aureus NCTC8325 genome.";
RL   Submitted (JAN-2006) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: Acts on both serine and threonine, and properly
CC       considered as a hydroxy amino acid deaminase (By similarity).
CC   -!- CATALYTIC ACTIVITY: L-threonine = 2-oxobutanoate + NH(3).
CC   -!- COFACTOR: Pyridoxal phosphate (By similarity).
CC   -!- PATHWAY: Amino-acid degradation; L-threonine degradation via
CC       propanoate pathway; propanoate from L-threonine: step 1/4.
CC   -!- SIMILARITY: Belongs to the serine/threonine dehydratase family.
