AbstractIron–sulfur (Fe–S) proteins play essential roles in all living organisms. The gastric pathogen Helicobacter pylori relies exclusively on the NIF system for biosynthesis and delivery of Fe–S clusters. Previously characterized components include two essential proteins, NifS (cysteine desulfurase) and NifU (scaffold protein), and a dispensable Fe–S carrier, Nfu. Among 38 proteins previously predicted to coordinate Fe–S clusters, two proteins, HP0207 (a member of the Nbp35/ApbC ATPase family) and HP0277 (previously annotated as FdxA, a member of the YfhL ferredoxin-like family) were further studied, using a bacterial two-hybrid system approach to identify protein–protein interactions. ApbC was found to interact with 30 proteins, including itself, NifS, NifU, Nfu and FdxA, and alteration of the conserved ATPase motif in ApbC resulted in a significant (50%) decrease in the number of protein interactions, suggesting the ATpase activity is needed for some ApbC-target protein interactions. FdxA was shown to interact with 21 proteins, including itself, NifS, ApbC and Nfu, however no interactions between NifU and FdxA were detected. By use of cross-linking studies, a 51-kDa ApbC-Nfu heterodimer complex was identified. Attempts to generate apbC chromosomal deletion mutants in H. pylori were unsuccessful, therefore indirectly suggesting the hp0207 gene is essential. In contrast, mutants in the fdxA gene were obtained, albeit only in one parental strain (26695). Taken together, these results suggest both ApbC and FdxA are important players in the H. pylori NIF maturation system.

AbstractOne of the peculiar aspects of living systems is the production and conservation of energy. This aspect is provided by specialized organelles, such as the mitochondria and chloroplasts, in developed living organisms. In primordial systems lacking specialized enzymatic complexes the energy supply was probably bound to the generation and maintenance of an asymmetric distribution of charged molecules in compartmentalized systems. On the basis of experimental evidence, we suggest that lipophilic quinones were involved in the generation of this asymmetrical distribution of charges through vectorial redox reactions across lipid membranes.

Introduction. Lipids are a widespread group of biologically active substances in nature, making up the bulk of the organic substances of all living organisms. They accumulate in plants in seeds, as well as in fruits and perform a number of vital functions: they are the main components of cell membranes and the energy reserve for the body.Aim. Study of neutral lipids of sown oats (Avena sativa L.).Materials and methods. The objects of the study were fruits (grains) of oats of the sown variety "Tashkent 1," harvested in the Republic of Uzbekistan. Results and discussions. Neutral lipids of oat grains have been found to contain 13 fatty acids with a predominance of the sum of oleic, linolenic and linoleic acids. The total degree of unsaturation was almost 78%. Absorption bands characteristic of these substances were observed in the IR spectrum of MEGC.Conclusion. According to the results of the NL analysis, oat grains consisted of triacylglycerides and free LCDs, which were accompanied by hydrocarbons, phytosterols, triterpenoids and tocopherols.

European Competition Law

AbstractOpt-in or opt-out? That is the basic question to be answered. The decision to promote actions of “opt-in” type as opposed to those of the “opt-out” type, for the sake of private autonomy, does not ensure the effective application of european competition law. On the contrary, it may decrease the application’s intensity and effectiveness. Recent reforms among European state members such as in the United Kingdom, Belgium, the Netherlands, Denmark and Norway are powerful indications that the opt-out principle may result in the effective implementation of competition law. There is no doubt that a mixed system (hybrid system), providing the court with the power to decide in favour of either the opt-in or the opt-out system, will result in better implementation of competition law. At the present time there are two pending cases in England (Dorothy Gibson and Mastercard) for which the decision on opt-out or opt-in are highly anticipated. Should the court decide, in one or both of the cases, on an opt-out approach, this will bring a momentous reevaluation of the entire collective redress concept.
