Structure-function relationships in mitochondrial complex I of the strictly aerobic yeast Yarrowia lipolytica.
The obligate aerobic yeast Yarrowia lipolytica has been established as a powerful model system for the analysis of mitochondrial complex I. Using a combination of genomic and proteomic approaches, a total of 37 subunits was identified. Several of the accessory subunits are predicted to be STMD (single transmembrane domain) proteins. Site-directed mutagenesis of Y. lipolytica complex I has provi...
متن کاملThe Complete Mitochondrial Genome of Yarrowia Lipolytica
We here report the complete nucleotide sequence of the 47.9 kb mitochondrial (mt) genome from the obligate aerobic yeast Yarrowia lipolytica. It encodes, all on the same strand, seven subunits of NADH: ubiquinone oxidoreductase (ND1-6, ND4L), apocytochrome b (COB), three subunits of cytochrome oxidase (COX1, 2, 3), three subunits of ATP synthetase (ATP6, 8 and 9), small and large ribosomal RNAs...
متن کاملAcyl-CoA oxidase is imported as a heteropentameric, cofactor-containing complex into peroxisomes of Yarrowia lipolytica
Five isoforms of acyl-CoA oxidase (Aox), designated Aox1p to Aox5p, constitute a 443-kD heteropentameric complex containing one polypeptide chain of each isoform within the peroxisomal matrix of the yeast Yarrowia lipolytica. Assembly of the Aox complex occurs in the cytosol and precedes its import into peroxisomes. Peroxisomal targeting of the Aox complex is abolished in a mutant lacking the p...
متن کاملSuperoxide radical formation by pure complex I (NADH:ubiquinone oxidoreductase) from Yarrowia lipolytica.
Generation of reactive oxygen species (ROS) is increasingly recognized as an important cellular process involved in numerous physiological and pathophysiological processes. Complex I (NADH:ubiquinone oxidoreductase) is considered as one of the major sources of ROS within mitochondria. Yet, the exact site and mechanism of superoxide production by this large membrane-bound multiprotein complex ha...
متن کاملActivating and Elucidating Metabolism of Complex Sugars in Yarrowia lipolytica.
The oleaginous yeast Yarrowia lipolytica is an industrially important host for production of organic acids, oleochemicals, lipids, and proteins with broad biotechnological applications. Albeit known for decades, the unique native metabolism of Y. lipolytica for using complex fermentable sugars, which are abundant in lignocellulosic biomass, is poorly understood. In this study, we activated and ...
