IntEnz Enzyme Nomenclature


Accepted name:
aconitate Δ-isomerase
Other name:
aconitate isomerase
Systematic name:
aconitate Δ23-isomerase



cis-Aconitate is used to designate the isomer (Z)-prop-1-ene-1,2,3-tricarboxylate. This isomerization could take place either in a direct cis-trans interconversion or by an allylic rearrangement; the enzyme has been shown to catalyse the latter change.
