1. Enzymatic reactions catalyzed by wild-type and mutant IDH enzymes.
Enzymatic reactions catalyzed by wild-type and mutant IDH enzymes. Top: wild-type IDH1 and IDH2 convert isocitrate to α-KG and CO2, with concomitant production of NADPH from NADP. Bottom: tumor-associated mutant IDH1 and IDH2 enzymes convert α-KG to D2HG, with concomitant production of NADP from NADPH. D2HG is a chiral molecule very similar in structure to α-KG. The chiral center in D2HG is denoted by *.
