'''ISOCITRATE DEHYDROGENASE Y160F MUTANT STEADY-STATE INTERMEDIATE COMPLEX (LAUE DETERMINATION)'''<br />


==Overview==
==ISOCITRATE DEHYDROGENASE Y160F MUTANT STEADY-STATE INTERMEDIATE COMPLEX (LAUE DETERMINATION)==
Site-directed mutagenesis and Laue diffraction data to 2.5 A resolution, were used to solve the structures of two sequential intermediates formed, during the catalytic actions of isocitrate dehydrogenase. Both, intermediates are distinct from the enzyme-substrate and enzyme-product, complexes. Mutation of key catalytic residues changed the rate determining, steps so that protein and substrate intermediates within the overall, reaction pathway could be visualized.
