during sugar starvation arising from the exposure of wild-type plants to darkness, autophagic transport of chloroplast stroma, which contains most of the proteins in a leaf, into the vacuolar lumen is induced within 2 days. During this time, the level of soluble proteins, primarily Rubisco (ribulose-1,5-bisphosphate carboxylase/oxygenase), decreases and the amount of free amino acid increases. In dark-treated autophagy-defective (atg) mutants, the decrease of soluble proteins is suppressed, which results in the compromised release of basic amino acids, branched-chain amino acids (BCAAs) and aromatic amino acids. The impairment of BCAA catabolic pathways in the knockout mutants of the electron transfer flavoprotein (ETF)/ETF:ubiquinone oxidoreductase (etfqo) complex and the electron donor protein isovaleryl-CoA dehydrogenase (ivdh) cause a reduced tolerance to dark treatment similar to that in the atg mutants. The enhanced accumulation of BCAAs in the ivdh and etfqo mutants during the dark treatment is reduced by additional autophagy deficiency. These results indicate that vacuolar protein degradation via autophagy serves as an adaptive response to disrupted photosynthesis by providing substrates to amino acid catabolic pathways, including BCAA catabolism mediated by IVDH and ETFQO.

BCAA transaminase 2 (BCAT2) and the branched-chain alpha2-oxo acid dehydrogenase complex subunit E1A1 (BCKDH E1A1) are involved in BCAA catabolism by providing substrates to enzyme IVDH. During sugar starvation arising from the exposure of wild-type plants to darkness, autophagic transport of chloroplast stroma, which contains most of the proteins in a leaf, into the vacuolar lumen is induced within 2 days. During this time, the level of soluble proteins, primarily Rubisco (ribulose-1,5-bisphosphate carboxylase/oxygenase), decreases and the amount of free amino acid increases. Vacuolar protein degradation via autophagy serves as an adaptive response to disrupted photosynthesis by providing substrates to amino acid catabolic pathways, including BCAA catabolism mediated by IVDH and ETFQO, involving the isovaleryl-CoA dehydrogenase (ivdh). Autophagy and amino acid catabolism are important in the plant response to sugar starvation. Relationship between autophagy and amino acid catabolism via the ETF/ETFQO system, overview |

isovaleryl-CoA dehydrogenase is an important enzyme in branched chain amino acid metabolism.

a G376V molecular defect of isovaleryl-CoA dehydrogenase, IVD, causes IVD deficiency which is responsible for the isovaleric acid-emanating skunk mutant odorous phenotype with prepupal lethality of the silkworm, molecular modelling, overview. The sku larvae begins emanating isovaleric acid odour from the first day after hatching, but does not show any signs of developmental abnormality until the onset of spinning. The mutants start spinning after the normal duration of the final instar, 6-8 days, but stop after a short time and develop a very thin cocoon. They eventually die without becoming pupae in about a week after spinning |
