In enzymology, a methylitaconate Δ-isomerase (EC 5.3.3.6) is an enzyme that catalyzes the chemical reaction

methylitaconate {\displaystyle \rightleftharpoons } 2,3-dimethylmaleate

Hence, this enzyme has one substrate, methylitaconate, and one product, 2,3-dimethylmaleate.

This enzyme belongs to the family of isomerases, specifically those intramolecular oxidoreductases transposing C=C bonds. The systematic name of this enzyme class is methylitaconate Delta2-Delta3-isomerase. This enzyme is also called methylitaconate isomerase. This enzyme participates in c5-branched dibasic acid metabolism.
