d-aa deaminase
Description beta-hydroxy D-amino acid ammonia-lyase (4.3.1.-)
Alternative names beta-hydroxy D-amino acid deaminase;
D-serine deaminase;
D-phenylserine deaminase;
beta-hydroxy D-amino acid acid dehydratase.
Catalyzed reaction D-serine = pyruvate + NH(3).
D-phenylserine = phenylpyruvate + NH(3).
Cofactor Pyridoxal-phosphate and Mn(II).
Comments A pyridoxal-phosphate protein that is activated by divalent metal cations (e.g., Zn2+, Cu2+ or Co2+). The enzyme acts on the D-forms of β-hydroxy-α-amino acids, such as D-serine, D-threo-phenylserine and D-threonine.
