The hyperthermophilic bacterium Thermotoga maritima MSB8 possesses a reverse gyrase whose enzymatic properties are very similar to those of archaeal reverse gyrases. It catalyzes the positive supercoiling of the DNA in an Mg2+- and ATP-dependent process. Its optimal temperature of activity is around 90 degrees C, and it is highly thermostable. We have cloned and DNA sequenced the corresponding ...
Shikimate dehydrogenase (SDH), which catalyses the NADPH-dependent reduction of 3-dehydroshikimate to shikimate in the shikimate pathway, is an attractive target for the development of herbicides and antimicrobial agents. Structural analysis of a SDH from Thermotoga maritima encoded by the Tm0346 gene was performed to facilitate further structural comparisons between the various shikimate dehyd...
Cultivated beets, including leaf garden fodder and sugar which belong to the species Beta vulgaris L., are economically important edible crops that have been originated from a halophytic wild ancestor, maritima L. (sea beet or beet). Salt drought major abiotic stresses, limit crop growth production most studied in beets compared other environmental stresses. Characteristically, salt- drought-to...
Thermophily is thought to be a primitive trait, characteristic of early forms of life on Earth, that has been gradually lost over evolutionary time. The genus Bacillus provides an ideal model for studying the evolution of thermophily as it is an ancient taxon and its contemporary species inhabit a range of thermal environments. The thermostability of reconstructed ancestral proteins has been us...
Thermotoga maritima (T. maritima) is a typical thermophile, and its proteome response to environmental temperature changes has yet to be explored. This study aims to uncover the temperature-dependent proteins of T. maritima using comparative proteomic approach. T. maritima was cultured under four temperatures, 60°C, 70°C, 80°C and 90°C, and the bacterial proteins were extracted and electrophore...
Heat-shock locus VU (HslVU) is an ATP-dependent proteolytic system and a prokaryotic homolog of the proteasome. It consists of HslV, the protease, and HslU, the ATPase and chaperone. We have cloned, sequenced and expressed both protein components from the hyperthermophile Thermotoga maritima. T. maritima HslU hydrolyzes a variety of nucleotides in a temperature-dependent manner, with the optimu...
UNLABELLED • PREMISE OF THE STUDY Microsatellite primers were developed in the beach plum, Prunus maritima, to investigate the genetic composition of remaining populations in need of conservation and, in future studies, to determine its relation to P. maritima var. gravesii. • METHODS AND RESULTS Fourteen primer pairs were identified and tested in four populations throughout the species' ge...
Periodontitis is very prevalent worldwide and is one of the major causes of tooth loss in adults. About 80% of the worldwide population use medicinal plants for their health care. Stemodia maritima L. (S. maritima) antioxidant and antimicrobial effects in vitro as well as anti-inflammatory properties. Herein, the potential therapeutic effect of S. maritima was assessed in rats subjected to expe...
