Fumarate Hydratase (Fumarase)

Fumarase is an enzyme of the citric acid cycle, glyoxylate cycle, and urea cycle that catalyzes addition of water to the double bond of fumarate to form L-malate.

> Fumarate + H 2O <=> L-Malate ( = -3.8 kJ/mol).

The enzyme is stereospecific, working only on the trans isomer.
