Reaction: L-allo-threonine = glycine + acetaldehyde
Systematic name: L-allo-threonine acetaldehyde-lyase (glycine-forming)
Comments: Requires pyridoxal phosphate. This enzyme, characterized from the bacterium Aeromonas jandaei, is specific for L-allo-threonine and can not act on either L-threonine or L-serine. Different from EC 188.8.131.52, L-threonine aldolase, and EC 184.108.40.206, low-specificity L-threonine aldolase. A previously listed enzyme with this name, EC 220.127.116.11, was deleted in 1971 after it was found to be identical to EC 18.104.22.168, glycine hydroxymethyltransferase.
