The breadth and depth of archaeal biology has exponentially increased since the pioneering work of Carl Woese revealed that the Archaea represent a distinct and diverse division of life. No one discip...
Microbial Domains in the Ocean: A Lesson from the Archaea     Archaea  Ocean       font style='font-size:12px;'> 2015/7/22
Microbial life thrives in virtually every habitat imaginable in the ocean, from the scalding temperatures found at hydrothermal vents, to frigid environments in and under polar sea ice, to high-pressu...
Dissimilatory iron-reduction in hyperthermophilic (Topt > 80°C) Archaea appears to be a ubiquitous, conserved, and possibly ancient metabolism that remains largely unknown. This investigation sought t...
Methanogenic archaea possess unusual seryl-tRNA synthetases (SerRS), evolutionarily distinct from the SerRSs found in other archaea, eucaryotes and bacteria. Our recent X-ray structural analysis of ...
Aminoacyl-tRNA Synthesis in Methanogenic Archaea     aminoacyl-tRNA  methanogenic Archaea  evolution  tRNA  translation       font style='font-size:12px;'> 2009/3/20
Aminoacyl-tRNA synthetases (AARSs) are essential for faithful translation of the genetic code and have long been studied intensively. Major discoveries explained basic principles of how amino acids ar...
Anaerobic oxidation of methane (AOM) is the main process responsible for the removal of methane generated in Earth's marine subsurface environments. However, the biochemical mechanism of AOM remains e...
The methanogenic archaeal community, methane production, and carbon isotopic fractionation were studied in the profundal sediments of oligotrophic Lake Stechlin. Because the water column of oligotroph...
This study examined the abundance, cell size, and activity of Bacteria and Archaea in the Chukchi Sea and the Canada Basin of the western Arctic Ocean in the spring (May-June) and summer (July-August)...
We determined the distribution and activity of the major prokaryotic groups (Bacteria, Cren-, and Euryarchaeota) inhabiting the deep water masses of the North Atlantic by following the path of the Nor...
We used 49,6-diamidino-2-phenylindole (DAPI) staining and fluorescent in situ hybridization to examine total bacterioplankton and archaeal distributions in surface waters and in deeper nepheloid...
Polyribonucleotide probes targeting planktonic archaeal (Group I and II) and bacterial rRNA revealed that Archaea comprised a significant fraction of total prokaryote cell abundance in the marine wate...
