Probing the intracellular proteome of Thermotoga maritima and Caldicellulosiruptor saccharolyticus in pure and co-culture affords a global investigation into the machinery and mechanisms enduring inside the bacterial thermophilic cell at the time of harvest. The second of a two part study, employing GeLC-MS(2) a variety of proteins were confidently identified with <1% false discovery rate, and ...

Octaprenyl pyrophosphate synthase (OPPs) catalyzes the chain elongation of farnesyl pyrophosphate (FPP) via consecutive condensation reactions with five molecules of isopentenyl pyrophosphate (IPP) to generate all-trans C40-octaprenyl pyrophosphate. The polymer forms the side chain of ubiquinone that is involved in electron transport system to produce ATP. Our previous study has demonstrated th...

Homology models of the E. coli and T. maritima chemotaxis protein CheW were constructed to assess the quality of structural predictions and their applicability in chemotaxis research: i) a model of E. coli CheW was constructed using the T. maritima CheW NMR structure as a template, and ii) a model of T. maritima CheW was constructed using the E. coli CheW NMR structure as a template. The confor...

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 genome sequence of the hyperthermophilic bacterium Thermotoga maritima encodes a number of glycosyl hydrolases. Many of these enzymes have been shown in vitro to degrade specific glycosides that presumably serve as carbon and energy sources for the organism. However, because of the broad substrate specificity of many glycosyl hydrolases, it is difficult to determine the physiological substr...

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...

The chromosome of Thermotoga maritima strain MSB8 was found to have an 8,870-bp region that is not present in its published sequence. The isolate that was sequenced by The Institute for Genomic Research (TIGR) in 1999 is apparently a laboratory variant of the isolate deposited at the Deutsche Sammlung von Mikroorganismen und Zellkulturen (DSM 3109) in 1986. This newly sequenced region from the ...
