Reaction: L-threonine = glycine + acetaldehyde
Other name(s): L-threonine acetaldehyde-lyase
Systematic name: L-threonine acetaldehyde-lyase (glycine-forming)
Comments: A pyridoxal-phosphate protein. This enzyme is specific for L-threonine and can not utilize L-allo-threonine. Different from EC 4.1.2.49, L-allo-threonine aldolase, and EC 4.1.2.48, low-specificity L-threonine aldolase.
