General Information

EC Number General Information Comment Organism
1.5.5.1 malfunction a small number of conidia are formed by ETF and ETFDH deletion mutants growing on different media, the conidial germination and appressoria formation on hydrophobic surface do not show any variations compared to the wild-type. Sprayed onto live barley and rice seedlings, the mutant conidia are almost completely non-pathogenic, despite producing a few non-extended necroses on the host surface. ETF and ETFDH mutants display growth and conidiation defects. ETF mutant etfb- cells exhibit reduced turgor pressure in 2-4 M glycerol, reduced ATP synthesis, and the ETF mutant etfb- is more sensitive to host oxidative stress (by H2O2 in host cells). ETF mutant etfb- shows lipid body accumulation. Phenotypes, overview Pyricularia oryzae
1.5.5.1 physiological function electron-transferring flavoprotein (ETF) and its dehydrogenase (ETFDH) are highly conserved electron carriers which mainly function in mitochondrial fatty acid beta oxidation. Besides catalyzing dehydrogenation, acyl-CoA dehydrogenases also transfer electrons to an electron-transferring flavoprotein (ETF), which, through the electron-transferring flavoprotein dehydrogenase (ETFDH), finally delivers the electrons to the ubiquinone pool in the terminal respiratory system for ATP synthesis. Thus, ETF and ETFDH link the fatty acids oxidation with respiratory system Pyricularia oryzae
