1. Mechanisms for control of nucleoside triphosphate hydrolysis. Effects of DNA and RNA co-factors
Abstract : In energetically unfavourable biological processes "protein machines" utilize chemical energy from the hydrolysis of high-energy phosphate bonds. Thus, the hydrolysis of a nucleoside triphosphate (NTP) to nucleoside diphosphate (NDP) with the release of free orthophosphate results in a liberation of energy. READ MORE

2. Computational identification of RNA and protein components from the Signal Recognition Particle
Abstract : Problem. The signal recognition particle (SRP) is a ribonucleoprotein particle that targets proteins to the endoplasmic reticulum in eukaryotes, to the plasma membrane in Archaea and Bacteria and to the thylakoid membrane in chloroplasts of photosynthetic organisms. It has one RNA component and 1 6 proteins. READ MORE

3. Membrane Protein Biogenesis in Escherichia coli : A proteomics approach
Abstract : In the bacterium Escherichia coli all proteins are synthesized in the cytoplasm. However, at least 25% of them then need to be exported to another cellular compartment where they exert their function. E. coli has several different targeting pathways to ensure the correct localization of its proteins. READ MORE

4. Ribosome Associated Factors Recruited for Protein Export and Folding
Abstract : Protein folding and export to the membrane are crucial events in the cell. Both processes may be initiated already at the ribosome, assisted by factors that bind to the polypeptide as it emerges from the ribosome. READ MORE

5. Involvement of Rel and GATA transcription factors in the regulation of antimicrobial peptide gene expression in Drosophila melanogaster
Abstract : Insects posses a powerful immune system related to the innate immune reactions present in vertebrates. When insects are infected by bacteria or other microorganisms, a vast production of different antimicrobial peptides is activated. The expression of antimicrobial peptides is regulated at the level of transcription. READ MORE
