Abstract excerpt

• Isopropylmalate dehydrogenases (IPMDHs) catalyze the oxidative decarboxylation of 3-isopropylmalate (3-IPM) in leucine biosynthesis in microorganisms. The Arabidopsis thaliana genome contains three putative IPMDH genes. • IPMDH2 and IPMDH3 proteins exhibited significantly higher activity toward 3-IPM than IPMDH1, which is indicative of a pivotal role in leucine biosynthesis. Single mutants of IPMDH2 or IPMDH3...
