In the genome of the hyperthermophilic bacterium Thermotoga maritima, TM0504 encodes a putative signaling peptide implicated in population density-dependent exopolysaccharide formation. Although not noted in the original genome annotation, TM0504 was found to colocate, on the opposite strand, with the gene encoding ssrA, a hybrid of tRNA and mRNA (tmRNA), which is involved in a trans-translatio...

MreB, a major component of the recently discovered bacterial cytoskeleton, displays a structure homologous to its eukaryotic counterpart actin. Here, we study the assembly and mechanical properties of Thermotoga maritima MreB in the presence of different nucleotides in vitro. We found that GTP, not ADP or GDP, can mediate MreB assembly into filamentous structures as effectively as ATP. Upon Mre...

The crystal structure of the thermostable indoleglycerol-phosphate synthase from Thermotoga maritima (tIGPS) was determined at 2.5 A resolution. It was compared with the structures of the thermostable sIGPS from Sulfolobus solfataricus and of the thermolabile eIGPS from Escherichia coli. The main chains of the three (beta alpha)(8)-barrel proteins superimpose closely, and the packing of side ch...

The RNA3-encoded p25 protein of beet necrotic yellow vein virus (BNYVV) is responsible for the production of rhizomania symptoms of sugar beet roots (Beta vulgaris subsp. vulgaris). Here, it was found that the presence of the p25 protein is also associated with the resistance response in rub-inoculated leaves of sugar beet and wild beet (Beta vulgaris subsp. maritima) plants. The resistance phe...

Mangrove communities provide habitat for many terrestrial and aquatic species and act as nurseries and breeding grounds for fish, crustaceans, and birds. They also protect coastal areas from erosion and storm events. However, globally 35% of mangrove habitat has been degraded or destroyed, making mangroves one of the most endangered ecosystems on earth. Thus, there is a demand for methods to re...

Petroleum ether, chloroform and methanol extracts of the whole plant of Artemisia maritima Linn were studied in vitro and in vivo for antitrypanosomal activity against Trypanosoma brucei brucei in Swiss albino mice. The extracts were also screened for phytochemicals/secondary metabolites. All the extracts showed trypanocidal activity against T. brucei brucei in vitro with the petroleum ether ex...
