B6db activities:
Description low-specificity L-threonine aldolase
Alternative names L-threonine/L-allo-threonine acetaldehyde-lyase (glycine-forming);
Catalyzed reaction L-threonine = glycine + acetaldehyde L-allo-threonine = glycine + acetaldehyde
Cofactor Pyridoxal-phosphate.
Comments Requires pyridoxal phosphate. The low-specificity L-threonine aldolase can act on both L-threonine and L-allo-threonine. The enzyme from Escherichia coli can also act on L-threo-phenylserine and L-erythro-phenylserine. The enzyme can also catalyse the aldol condensation of glycolaldehyde and glycine to form 4-hydroxy-L-threonine, an intermediate of pyridoxal phosphate biosynthesis. Different from EC, L-threonine aldolase, and EC, L-allo-threonine aldolase.
