Project description:Recent genomic studies revealed that mitochondria from mistletoe species appear to lack a major amount of genes, indicating a possible loss of the NADH ubiquinone oxidoreductase (complex I) which forms an essential part of the mitochondrial Oxidative Phosphorylation System (OXPHOS). This dataset is used for profiling of the mitochondrial complexome from European mistletoe, Viscum album and gives biochemical evidence for a lack of complex I as well as a unique composition of OXPHOS in Viscum album.
Project description:Viscum album is known for its special mode of cellular respiration. It lacks the mitochondrial NADH dehydrogenase complex (complex I of the respiratory chain) and has restricted capacities to generate mitochondrial adenosine triphosphate (ATP). We here present an investigation of the V. album energy metabolism taking place in mitochondria. Mitochondria were purified from young V. album leaves and membrane bound protein complexes characterized by Blue native polyacrylamide gel electrophoresis as well as by the complexome profiling approach. Proteins were systematically identified by label-free quantitative shotgun proteomics.

It lacks the mitochondrial NADH dehydrogenase complex (complex I of the respiratory chain) and has restricted capacities to generate mitochondrial adenosine triphosphate (ATP). We here present an investigation of the V. album energy metabolism taking place in the chloroplasts. Thylakoids were purified from young V. album leaves and membrane bound protein complexes characterized by Blue native polyacrylamide gel electrophoresis as well as by the complexome profiling approach. Proteins were systematically identified by label-free quantitative shotgun proteomics.
