Low-specificity L-threonine aldolase (EC 4.1.2.48, LtaE) is an enzyme with systematic name L-threonine/L-allo-threonine acetaldehyde-lyase (glycine-forming).[1][2][3][4][5] This enzyme catalyses the following chemical reaction
- (1) L-threonine glycine + acetaldehyde
- (2) L-allothreonine glycine + acetaldehyde
This enzyme requires pyridoxal phosphate.
