Metabolomicsmetabolomics Analysis in Cecal Samples
Targeted LC/MS Metabolomics. Cecal contents were lyophilized overnight and approximately 2.5-5 mg was homogenized in 250 µL of 50% acidified acetonitrile (0.3% formic acid) for targeted LC/MS/MS metabolomics (acylcarnitines, amino acids, organic acids, nucleotides, and CoAs) according to validated, ...

ProteomicsIdentification of a previously uncharacterised polypeptide component of the Rhodopseudomonas palustris light-harvesting 2 complex.
The purple bacterium Rhodopseudomonas palustris is a model organism for dissecting the energy and electron transfer processes that have evolved in phototrophic organisms. This bacterium is of particular interest because, in addition to driving its metabolism via solar energy capture, it is capable o...

ProteomicsProteomic comparison of photosynthetic reaction centre-light harvesting 1 complexes in wild-type, protein-W knockout and His-tagged protein-W strains of Rhodopseudomonas palustris.
Rhodopseudomonas palustris is a species of purple phototrophic bacterium. In these species, solar energy is captured by reaction centre-light harvesting 1 (RC-LH1) complexes which reside in membranes within the cells. The RC comprises three protein subunits: H, M, L and is encircled by a ring of LH1...

ProteomicsTwo unrelated 8-vinyl reductases ensure production of mature chlorophylls in Acaryochloris marina
The aim of this project is to identify, by bottom-up proteomic analysis, one or both representatives of two classes of 8-vinyl reductase in an Acaryochloris marina cell lysate. This enzyme is responsible for the conversion of the C8 vinyl group in the chlorophyll precursor Mg-divinyl-protochlorophyl...
