IUBMB Enzyme Nomenclature


Accepted name: L-threonine aldolase

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, L-allo-threonine aldolase, and EC, low-specificity L-threonine aldolase.
