isovaleric acidemia is a rare recessive autosomal disorder, caused by isovaleryl-CoA dehydrogenase (IVD) deficiency. Molecular analysis of their IVD gene reveals six mutation profiles: R21H, R363C, H100R, S97F, C30Y and Y371C (common recurring missense mutation)

E246Q
site-directed mutagenesis, the recombinant IVDH enzyme mutant is obtained as an apoprotein, the protein is fully reconstituted by incubation with flavin adenine dinucleotide (FAD) at a ratio 1:20 (IVDH: FAD) molar excess. The reconstituted E246Q IVDH has no activity for isovaleryl-CoA. The mutant IVDH is unable to form charge transfer complex as a result of altering catalytic residue E246

knockout mutants atg10-1, atg5-1, and atg2-1, as well as ivdh-1 and etfqo-1 mutants, phenotypes, overview. Dark-induced increases in specific amino acid levels are compromised in atg mutants. Comparison of the amino acid levels between ivdh-1 or etfqo-1 mutants and the wild-type shows that total amino acid levels increase similarly after the dark treatment among those plants, mainly caused by increases in the BCAAs, basic amino acids, aromatic amino acids and Asn. The dark-induced increase of Glu is suppressed in ivdh-1 and etfqo-1. Among the individual amino acids that do not increase in the dark-treated wild-type, the decrease in alanine levels is exacerbated in both ivdh-1 and etfqo-1. These results show the attenuation of BCAA catabolism in the mutants. The accumulation of BCAAs after 2 days of dark treatment is enhanced in ivdh-1 and etfqo-1 compared with to wild-type supporting the suggestion that BCAAs are catabolized via IVDH and the ETF/ETFQO system from an early period of dark treatment. The ivdh-1 and etfqo-1 mutations do not affect the dark-induced increases in the levels of basic amino acids (Lys, Arg, and His) and aromatic amino acids (Phe, Tyr, and Trp) compared with to wild-type plants
