gene CG12140, mapping and cloning of ETF:QO alleles, expression of the two subunits ETFA and ETFB in Escherichia coli strain BL21 | Drosophila melanogaster |
Protein Variants | Comment | Organism |

additional information | three independent mutant alleles, corresponding to three distinct point mutations in ETF:QO, are lethal as a result of a specific knockdown of FAD binding by direct disruption of the cofactor binding motif within the nucleotide binding Rossmann fold, a nucleotide binding structural domain also present in ETF:QO, which comprises a beta-strand connected by a short loop to an alpha-helix, and includes an expanded sequence motif (V/IxGx12GxxGxxxG/A) that affords both FAD binding and stabilisation of the secondary structure elements involved, overview | Drosophila melanogaster |

malfunction | ETF:QO mutant alleles faileto identify developmental defects, but a complete dysfunction of the ETF:QO protein leads to abnormal mitochondrial fatty acid oxidation. Acylcarnitine levels in ETF:QO mutant embryos display a profile typical of MADD, i.e. multiple acyl-CoA dehydrogenase deficiency, a metabolic disease of bet-oxidation, with a broad range of clinical phenotypes, varying from embryonic lethal to mild forms in humans. Fly mutant phentypes, overview | Drosophila melanogaster |
additional information | the Rossmann fold is a nucleotide binding structural domain present in ETF:QO, it comprises a beta-strand connected by a short loop to an alpha-helix, and includes an expanded sequence motif (V/IxGx1-2GxxGxxxG/A) that affords both FAD binding and stabilisation of the secondary structure elements involved | Drosophila melanogaster |
physiological function | the enzyme is maternally required for Drosophila embryogenesis | Drosophila melanogaster |
