IntEnz Enzyme Nomenclature


Accepted name:
L-threonine aldolase
Other name:
L-threonine acetaldehyde-lyase
Systematic name:
L-threonine acetaldehyde-lyase (glycine-forming)




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.
