MD Simulation Studies of Fumarase Reveal Thermo Dynamical Stability

Fumarase enzyme is known to catalyse the stereo specific inter conversion of fumarate to L-malate which is a part of the Krebs cycle. Despite the biological significance and importance of this enzyme, the reaction mechanism of fumarase is not completely understood or known. In this context an experiment on molecular dynamics simulation was carried out for at least 10 nanoseconds molecular dynamics simulation run using Nano Scale Molecular Dynamics program implemented in Discovery Studio 4.0. The trajectory analysis of various energy parameters revealed the thermo dynamical stability of the enzyme. The present findings may aid in understanding the biological significance of this enzyme.
