Comments [?]

Function Catalyzes cis-trans isomerization of the C2-C3 double bond in maleate to yield fumarate.
Catalytic activity RHEA:13169: maleate = fumarate
EC 5.2.1.1
Subunit Homodimer.
Miscellaneous Reaction is initiated by nucleophilic attack of cysteine at the double bond, yielding a covalent succinylcysteine-like intermediate.
Similarity Belongs to the maleate isomerase family.
