Pressure-enhanced activity and stability of a hyperthermophilic protease from a deep-sea methanogen.
We describe the properties of a hyperthermophilic, barophilic protease from Methanococcus jannaschii, an extremely thermophilic deep-sea methanogen. This enzyme is the first protease to be isolated from an organism adapted to a high-pressure-high-temperature environment. The partially purified enzyme has a molecular mass of 29 kDa and a narrow substrate specificity with strong preference for le...
متن کاملMethanocaldococcus bathoardescens sp. nov., a hyperthermophilic methanogen isolated from a volcanically active deep-sea hydrothermal vent.
A hyperthermophilic methanogen, strain JH146(T), was isolated from 26 °C hydrothermal vent fluid emanating from a crack in basaltic rock at Marker 113 vent, Axial Seamount in the northeastern Pacific Ocean. It was identified as an obligate anaerobe that uses only H2 and CO2 for growth. Phylogenetic analysis based on 16S rRNA gene sequences showed that the strain is more than 97% similar to othe...
متن کاملCell proliferation at 122 degrees C and isotopically heavy CH4 production by a hyperthermophilic methanogen under high-pressure cultivation.
We have developed a technique for cultivation of chemolithoautotrophs under high hydrostatic pressures that is successfully applicable to various types of deep-sea chemolithoautotrophs, including methanogens. It is based on a glass-syringe-sealing liquid medium and gas mixture used in conjunction with a butyl rubber piston and a metallic needle stuck into butyl rubber. By using this technique, ...
متن کاملDrosophila melanogaster: a genome sequenced.
The release of the full genome sequence of Drosophila melanogaster in March of 2000 must be heralded both as a milestone in Drosophila biology and genetics and as a triumph of modern biotechnology. But the true value of this accomplishment can be found in its beginnings, during a plenary session at a 1978 Drosophila meeting in La Jolla, California. The first speaker of the session was peppered ...
متن کاملRice blast fungus sequenced
Rice (Oryza sativa L.) is a major staple food crop for half of the world’s population. The International Rice Research Institute, Philippines, estimates that in order to feed the growing global population, rice production must increase by another one-third by the year 2020. Magnaporthe grisea (anamorph, Pyricularia oryzae) causes rice blast disease (Figure 1) and is the most destructive pathoge...
