▪ Abstract Molecular chaperones, including the heat-shock proteins (Hsps), are a ubiquitous
feature of cells in which these proteins cope with stress-induced denaturation of other …

▪ Abstract The recent recognition of a potentially vast, unexplored hot microbial biosphere
associated with active volcanism along the global mid-ocean ridge network has …

We have considered a wide array of scenarios for Europa's chemical evolution in an attempt
to explain the presence of ice and hydrated materials on its surface and to understand the …

Thermophilic microbial inhabitants of active seafloor and continental hot springs populate
the deepest branches of the universal phylogenetic tree, making hydrothermal ecosystems …

The study of enzymes isolated from organisms inhabiting unconventional ecosystems has
led to the realization that biocatalysis need not be constrained to mild conditions and can be …

Since the discovery of hyperthermophilic microbial activity in hydrothermal fluids recovered
from “smoker” vents on the East Pacific Rise, the widely accepted upper temperature limit for …

The field covered in this review is new; the first sequence of a gene encoding the molecular
chaperone Hsp70 and the first description of a chaperonin in the archaea were reported in …

We report that the halophilic archaeon Halobacterium sp. strain NRC-1 is highly resistant to
desiccation, high vacuum and 60 Co gamma irradiation. Halobacterium sp. was able to …

Enzymes synthesized by thermophiles (organisms with optimal growth temperatures> 60° C)
and hyperthermophiles (optimal growth temperatures> 80° C) are typically thermostable …

RecA and Rad51 proteins are essential for homologous recombination in Bacteria
andEukarya, respectively. Homologous proteins, called RadA, have been described for …
