IUBMB Enzyme Nomenclature


Accepted name: L-allo-threonine aldolase

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, L-threonine aldolase, and EC, low-specificity L-threonine aldolase. A previously listed enzyme with this name, EC, was deleted in 1971 after it was found to be identical to EC, glycine hydroxymethyltransferase.
