ISOCITRATE DEHYDROGENASE FROM E.COLI (MUTANT K230M), STEADY-STATE INTERMEDIATE COMPLEX DETERMINED BY LAUE CRYSTALLOGRAPHY
Overview
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.
