Enzyme Information
| 4.1.2.48 |
Low-specificity L-threonine aldolase.
based on mapping to UniProt P75823
(1) L-threonine = glycine + acetaldehyde. (2) L-allo-threonine = glycine + acetaldehyde.
-!- 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 catalyze the aldol condensation of glycolaldehyde and glycine to form 4-hydroxy-L-threonine, an intermediate of pyridoxal phosphate biosynthesis. -!- Different from EC 4.1.2.5 and EC 4.1.2.49.
