In vivo protein labeling with L-[35S]-methionine and analysis by two-dimensional gel electrophoresis revealed that the synthesis of 61 proteins was changed in response to 1O2. After 1O2 treatment, protein synthesis patterns were distinct from those after H2O2 treatment but similar to those after high light exposure. This indicates regulatory mechanisms selective for different reactive oxygen species (ROS) and a response to light partly mediated by 1O2. Analysis of mutant strains support that the response to 1O2 is regulated mainly by rpoE (sigma E), but also a modulation of the sigma E dependent response by other factors and the existence of sigma E independent responses. The involvement of the RNA chaperon Hfq in the 1O2 response implies a role of small regulatory RNAs.}, issn = {15353893}, keywords = {Bacterial Bacterial_Proteins Catalase Cations Divalent Electrophoresis Gel Gene_Expression_Regulation Host_Factor_1_Protein Hydrogen_Peroxide IFZ Light Messenger Mutation Protein_Biosynthesis Proteome RNA Reactive_Oxygen_Species Rhodobacter_sphaeroides Sigma_Factor Singlet_Oxygen Transcription_Factors Two-Dimensional } } @book{citeulike:498518, title = {Bioanalytik.}, author = {Friedrich Lottspeich and Haralabos Zorbas}, howpublished = {Hardcover}, month = {April}, publisher = {Spektrum Akademischer Verlag}, url = {http://www.amazon.com/exec/obidos/redirect?tag=citeulike-20\&path=ASIN/3827400414}, year = {1998}, biburl = {http://www.bibsonomy.org/bibtex/2c23c6ebc1519c9394d92baf0a8ea86a1/robert}, isbn = {3827400414}, priority = {2}, citeulike-article-id = {498518}, keywords = {no-tag } } @book{citeulike:500632, title = {Microcharacterization of Proteins}, author = {Roland Kellner and Friedrich Lottspeich and Helmut E.

Kellner, F. Lottspeich, H. E. Meyer Microcharacterization of Proteins Second Edition Proteomics the analysis of the whole set of proteins and their functions in a cell is based on the revolutionary developments which have been achieved in protein analysis during the last years. The number of finished genome projects is growing and in parallel there is a dramatically increasing need to identify the products of revealed genes. Acting on a micro level modern protein chemistry increases our understanding of biological events by elucidating the relevant structure-function relationships. The second edition of the successful title "Microcharacterization of Proteins" presents a current overview of modern protein analysis: From sample preparation to sequence analysis, mass spectrometry and bioinformatics it informs about the tools needed in protein research. This makes the book indispensable for everyone involved in proteomics! }}, comment = {Protein fragmentation (chemically and enzymatically)}, isbn = {3527300848}, citeulike-article-id = {500632}, priority = {2}, keywords = {protein-analysis } }
