What's a GeneRIF?

On the basis of a potential interaction between side chains of Cys-150 residues in IDH2 subunits in each tetramer of the enzyme, ligand binding assays of wild-type (IDH1/IDH2) and IDH1/IDH2(C150S) octameric enzymes were conducted.

Structural features of a ligand-free form of IDH2 suggest that formation of a disulfide bond during stationary phase in yeast transformants might stabilize an inactive form of the enzyme.

Structural studies of Saccharomyces cerevisiae mitochondrial NADP-dependent IDH2 in different enzymatic states reveal substantial conformational changes during the catalytic reactiion.
