ID 4.1.2.48 DE low-specificity L-threonine aldolase. CA (1) L-threonine = acetaldehyde + glycine. CA (2) L-allo-threonine = acetaldehyde + glycine. CC -!- The low-specificity L-threonine aldolase can act on both L-threonine CC and L-allo-threonine. CC -!- The enzyme from Escherichia coli can also act on L-threo-phenylserine CC and L-erythro-phenylserine. CC -!- The enzyme can also catalyze the aldol condensation of glycolaldehyde CC and glycine to form 4-hydroxy-L-threonine, an intermediate of CC pyridoxal phosphate biosynthesis. CC -!- Different from EC 4.1.2.5 and EC 4.1.2.49.
