Pyrobaculum
A genus of rod-shaped, almost rectangular ARCHAEA, in the family THERMOPROTEACEAE. Organisms are facultatively aerobic or strictly anaerobic, grow on various organic substrates, and are found in continental solfataras.
Thermoproteaceae
A family of THERMOPROTEALES consisting of variable length rigid rods without septa. They grow either chemolithoautotrophically or by sulfur respiration. The four genera are: PYROBACULUM; THERMOPROTEUS; Caldivirga; and Thermocladium. (From Bergey's Manual of Systematic Bacteriology, 2d ed)
Thermoproteus
A genus of obligately anaerobic ARCHAEA, in the family THERMOPROTEACEAE. They are found in acidic hot springs and water holes.
Crenarchaeota
A kingdom in the domain ARCHAEA comprised of thermoacidophilic, sulfur-dependent organisms. The two orders are SULFOLOBALES and THERMOPROTEALES.
Genome, Archaeal
The genetic complement of an archaeal organism (ARCHAEA) as represented in its DNA.
Pyrodictiaceae
A family of archaea, in the order DESULFUROCOCCALES consisting of anaerobic coccoid to disc-shaped cells. They grow either chemolithoautotrophically or by FERMENTATION. Three genera are recognized: Pyrodictium, Hyperthermus, and Pyrolobus.
Hydrogensulfite Reductase
Archaea
One of the three domains of life (the others being BACTERIA and Eukarya), formerly called Archaebacteria under the taxon Bacteria, but now considered separate and distinct. They are characterized by: (1) the presence of characteristic tRNAs and ribosomal RNAs; (2) the absence of peptidoglycan cell walls; (3) the presence of ether-linked lipids built from branched-chain subunits; and (4) their occurrence in unusual habitats. While archaea resemble bacteria in morphology and genomic organization, they resemble eukarya in their method of genomic replication. The domain contains at least four kingdoms: CRENARCHAEOTA; EURYARCHAEOTA; NANOARCHAEOTA; and KORARCHAEOTA.
Enzyme Stability
DNA, Archaeal
Deoxyribonucleic acid that makes up the genetic material of archaea.
RNA, Archaeal
Ribonucleic acid in archaea having regulatory and catalytic roles as well as involvement in protein synthesis.
Uracil-DNA Glycosidase
FMN Reductase
Molecular Sequence Data
Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.
Hot Springs
Habitat of hot water naturally heated by underlying geologic processes. Surface hot springs have been used for BALNEOLOGY. Underwater hot springs are called HYDROTHERMAL VENTS.
