A known 40 kbp bacteriophage insertion [2586000-2626000] is, surprisingly, not among the genomic fragments selected in the SWGB using this filter. Although the prophage is still perceptible on the Gene Map view (see a figure in the supplementary help web-pages), the OU parameters of the region do not differ markedly enough from the core sequence to be isolated automatically as a horizontally transferred region.. As the SWGB uses parameters that are based on comparison of local fragments to the global genomic average, strains with abundant insertions of homogenous DNA can confound this form of analysis. One example is the Methanosarcina acetivorans C2A genome which is composed of an estimated 25% of putatively horizontally acquired DNA, one of the highest amounts discovered to date [11]. As a result of these insertions, the genomic signature has been strongly influenced, resulting in a large amount of scatter and a poorly defined core genome on the plots. On the other hand, this type of ...

Methanogenesis, the biological production of methane, plays a pivotal role in the global carbon cycle and contributes significantly to global warming. The majority of methane in nature is derived from acetate. Here we report the complete genome sequence of an acetate-utilizing methanogen, Methanosarcina acetivorans C2A. Methanosarcineae are the most metabolically diverse methanogens, thrive in a broad range of environments, and are unique among the Archaea in forming complex multicellular structures. This diversity is reflected in the genome of M. acetivorans. At 5,751,492 base pairs it is by far the largest known archaeal genome. The 4524 open reading frames code for a strikingly wide and unanticipated variety of metabolic and cellular capabilities. The presence of novel methyltransferases indicates the likelihood of undiscovered natural energy sources for methanogenesis, whereas the presence of single-subunit carbon monoxide dehydrogenases raises the possibility of nonmethanogenic growth. ...
The factors controlling the relative abundances of Archaea and Bacteria in marine sediments are poorly understood. We determined depth distributions of archaeal and bacterial 16S rRNA genes by quantitative PCR at eight stations in Aarhus Bay, Denmark. Bacterial outnumber archaeal genes 10-60-fold in uppermost sediments that are irrigated and mixed by macrofauna. This bioturbation is indicated by visual observations of sediment color and faunal tracks, by porewater profiles of dissolved inorganic carbon and sulfate, and by distributions of unsupported 210Pb and 137Cs. Below the depth of bioturbation, the relative abundances of archaeal genes increase, accounting for one third of 16S rRNA genes in the sulfate zone, and half of 16S rRNA genes in the sulfate-methane transition zone and methane zone. Phylogenetic analyses reveal a strong shift in bacterial and archaeal community structure from bioturbated sediments to underlying layers. Stable isotopic analyses on organic matter and porewater ...

While ubiquitous among Archaea, and common in bacteria, the S-layers of diverse organisms have unique structural properties, including symmetry and unit cell dimensions, due to fundamental differences in their constituent building blocks.[14] Sequence analyses of S-layer proteins have predicted that S-layer proteins have sizes of 40-200 kDa and may be composed of multiple domains some of which may be structurally related. Since the first evidence of a macromolecular array on a bacterial cell wall fragment in the 1950s[15] S-layer structure has been investigated extensively by electron microscopy and medium resolution images of S-layers from these analyses has provided useful information on overall S-layer morphology. High-resolution structures of an archaeal S-layer protein (MA0829 from Methanosarcina acetivorans C2A) of the Methanosarcinales S-layer Tile Protein family and a bacterial S-layer protein (SbsB), from Geobacillus stearothermophilus PV72, have recently been determined by X-ray ...

The cytoplasmic hydrogenase (SHI) of the hyperthermophilic archaeon Pyrococcus furiosus is an NADP(H)-dependent heterotetrameric enzyme that contains a nickel-iron catalytic site, flavin, and six iron-sulfur clusters. It has potential utility in a range of bioenergy systems in vitro, but a major obstacle in its use is generating sufficient amounts. We have engineered P. furiosus to overproduce SHI utilizing a recently developed genetic system. In the overexpression (OE-SHI) strain, transcription of the four-gene SHI operon was under the control of a strong constitutive promoter, and a Strep-tag II was added to the N terminus of one subunit. OE-SHI and wild-type P. furiosus strains had similar rates of growth and H 2 production on maltose. Strain OE-SHI had a 20-fold higher transcription of the polycistronic hydrogenase mRNA encoding SHI, and the specific activity of the cytoplasmic hydrogenase was ∼10-fold higher when compared with the wild-type strain, although the expression levels of genes
The genes encoding the three subunits of the primary ABC transporter Ota of the methanogenic archaeon Methanosarcina mazei Gö1 were cloned in an expression vector (pBAD24) and transformed into the glycine betaine transport-negative mutant Escherichia coli MKH13. Ota was produced as demonstrated by Western blotting. Uptake studies revealed that Ota catalyzed the transport of glycine betaine in E. coli MKH13(pBAD-Ota) with a Km of 10±5 μM and a maximal velocity of 1.5±0.5 nmol min⁻¹ mg protein⁻¹. Transport was ATP dependent. Ota was activated by salinity gradients, but only marginally by sugar gradients across the membrane. Glycine betaine transport was inhibited to a small extent by an excess of dimethylglycin or proline betaine, but not by sarcosine or glycine ...
The coordinated activities of AlaAT and GDH have been proposed to play an important role in the maintenance of the redox balance during fermentative growth of P. furiosus(19). These activities result in a change in the relative flux of pyruvate to acetate formation toward alanine formation. Pyruvate is therefore used as a catabolic electron sink. Due to the important role AlaAT plays in this pathway, this enzyme was purified from P. furiosus and represents the first AlaAT purified from either an archaeon or a hyperthermophile.. Similar to the AlaAT from mesophilic sources, the active form of the enzyme was found to be a homodimer with a subunit molecular mass of 43.5 kDa (22, 34, 36). It has been reported that the AlaATs have a high substrate specificity and are only able to transaminate alanine or glutamate (22, 34, 36). The P. furiosus enzyme, however, was capable of utilizing aspartate and, to a much lesser extent, the branched-chain amino acids with α-ketoglutarate as the amino acceptor, ...

Archaea are best known in their capacities as extremophiles, i.e. micro-organisms able to thrive in some of the most drastic environments on Earth. The protein-based surface layer that envelopes many archaeal strains must thus correctly assemble and maintain its structural integrity in the face of the physical challenges associated with, for instance, life in high salinity, at elevated temperatures or in acidic surroundings. Study of archaeal surface-layer (glyco)proteins has thus offered insight into the strategies employed by these proteins to survive direct contact with extreme environments, yet has also served to elucidate other aspects of archaeal protein biosynthesis, including glycosylation, lipid modification and protein export. In this mini-review, recent advances in the study of archaeal surface-layer (glyco)proteins are discussed.

Introduction: Archaea comes from the greek word, archaio, meaning ancient (billions of years, and if you dont call that old, then I dont know what is). In order to fully understand the origins of Archaea, we must look at evolutionary history. From what we understand, all living forms have descended from a Universal ancestor, which appeared through spontaneous generation. The term spontaneous generation is generally used to explain what Europeans before 1668 believed to be the cause of life, indicating that every day, living organisms were created by non living things (such as mud). This should not be confused with the modern theory of the origin of life, that abiotic amino acids were generated in the primordial soup and spontaneously joined together to form LUCA ...

An evolutionary classification of genes from sequenced genomes that distinguishes between orthologs and paralogs is indispensable for genome annotation and evolutionary reconstruction. Shortly after multiple genome sequences of bacteria, archaea, and unicellular eukaryotes became available, an attempt on such a classification was implemented in Clusters of Orthologous Groups of proteins (COGs). Rapid accumulation of genome sequences creates opportunities for refining COGs but also represents a challenge because of error amplification. One of the practical strategies involves construction of refined COGs for phylogenetically compact subsets of genomes. New Archaeal Clusters of Orthologous Genes (arCOGs) were constructed for 41 archaeal genomes (13 Crenarchaeota, 27 Euryarchaeota and one Nanoarchaeon) using an improved procedure that employs a similarity tree between smaller, group-specific clusters, semi-automatically partitions orthology domains in multidomain proteins, and uses profile searches for
The archaeon Halobacterium NRC-1 is an extreme halophile that thrives in saturated brine environments such as the Dead Sea and solar salterns. It offers a versatile and easily assayed system for an array of well-coordinated physiologies that are necessary for survival in its harsh environment [1]. It has robust DNA repair systems that can efficiently reverse the damages caused by a variety of mutagens including UV radiation and desiccation/re-hydration cycles [2, 3]. Halobacterium NRC-1 adapts its metabolism to anaerobic conditions with the synthesis of bacterorhodopsin, which facilitates the conversion of energy from light into ATP. The completely sequenced genome of Halobacterium NRC-1 (containing ~2,600 genes) has provided insights into many of its physiological capabilities, however nearly half of all genes encoded in the halobacterial genome have no known function [4-7].. This work is intended to be a prototype for the development of a biological data integration system with a focus on ...
For comparison, host of NSV, AOA, was quantified using primers for archaeal amoA gene with a previous protocol (Park et al., 2008). Archaeal amoA gene could be detected in all the samples as pPolB gene. pPolB and amoA gene copies were quantified as described previously (Kim et al., 2019), using real-time PCR with CFX Connect Real-Time system (Bio-Rad Laboratories) using iQ SYBRGreen Supermix (Bio-Rad Laboratories) and built-in CFX manager software v3.0 (Bio-Rad Laboratories). AamoAF and AamoAR primers (Francis et al., 2005) were used with following PCR condition: 95°C (5 min), then 40 cycles at 95°C (30 sec), 55°C (30 sec), and 72°C (1.5 min). For quantification of viral pPolB gene, semi-nested real-time PCR was performed: the first PCR using primers 620F and 1880R with following PCR condition: first, 95°C (10 min), then 20 cycles at 95°C (30 sec), 55°C (30 sec), and 72°C (1.5 min); the second PCR using primers 620F and primer 950R (5-CATGGCRTAWGGATAWGCWGAATT-3) with the same thermal ...

Some Archaea thrive in extreme places such as in thermal pools, hot vents at the bottom of the sea, extremely salty water, and even in underground oil reserves. This book examines the diverse Archaea kingdom and the division of these organisms by their unusual biology into three main groups. It also explains why little in general is known about them, and why further classification of Archaea is so difficult.
The coupled nitrification-denitrification process plays a pivotal role in cycling and removal of nitrogen in aquatic ecosystems. In the present study, the communities of ammonia oxidizers and denitrifiers in the sediments of 2 basins (Guozhenghu Basin and Tuanhu Basin) of a large urban eutrophic lake (Lake Donghu) were determined using the ammonia monooxygenase subunit A (amoA) gene and the nitrite reductase gene. At all sites of this study, the archaeal amoA gene predominated over the bacterial amoA gene, whereas the functional gene for denitrification nirK gene far outnumbered the nirS gene. Spatially, compared with the Tuanhu Basin, the Guozhenghu Basin showed a significantly greater abundance of the archaeal amoA gene but less abundance of the nirK and nirS genes, while there was no significant difference of bacterial amoA gene copy numbers between the 2 basins. Unlike the archaeal amoA gene, the nirK gene showed a significant difference in community structure between the 2 basins. Archaeal ...

In marine sediments archaea often constitute a considerable part of the microbial community, of which the Deep Sea Archaeal Group (DSAG) is one of the most predominant. Despite their high abundance no members from this archaeal group have so far been characterized and thus their metabolism is unknown. Here we show that the relative abundance of DSAG marker genes can be correlated with geochemical parameters, allowing prediction of both the potential electron donors and acceptors of these organisms. We estimated the abundance of 16S rRNA genes from Archaea, Bacteria, and DSAG in 52 sediment horizons from two cores collected at the slow-spreading Arctic Mid-Ocean Ridge, using qPCR. The results indicate that members of the DSAG make up the entire archaeal population in certain horizons and constitute up to ~50% of the total microbial community. The quantitative data were correlated to 30 different geophysical and geochemical parameters obtained from the same sediment horizons. We observed a significant

Background Differential RNA-Seq (dRNA-Seq) is a recently developed method of performing primary transcriptome analyses that allows for the genome-wide mapping of transcriptional start sites (TSSs) and the identification of novel transcripts. Although the transcriptomes of diverse bacterial species have been characterized by dRNA-Seq, the transcriptome analysis of archaeal species is still rather limited. Therefore, we used dRNA-Seq to characterize the primary transcriptome of the model archaeon Haloferax volcanii. Results Three independent cultures of Hfx. volcanii grown under optimal conditions to the mid-exponential growth phase were used to determine the primary transcriptome and map the 5′-ends of the transcripts. In total, 4749 potential TSSs were detected. A position weight matrix (PWM) was derived for the promoter predictions, and the results showed that 64 % of the TSSs were preceded by stringent or relaxed basal promoters. Of the identified TSSs, 1851 belonged to protein-coding genes. ...
Provided herein are genetically engineered archaea. A genetically engineered archaea includes a heterologous polynucleotide that has a promoter operably linked to a coding region, where the coding region encodes a polypeptide having optimal activity below the optimum growth temperature (T.sub.opt) of the genetically engineered archaeon. Also provided herein are methods for using genetically engineered archaea and cell-free extracts of such genetically engineered archaea. In one embodiment, the methods include culturing a genetically engineered archaeon at a temperature that is at least 20.degree. C. below the T.sub.opt of the genetically engineered archaeon, such that the activity in the genetically engineered archaeon of a polypeptide encoded by the coding region is increased compared to the activity in the genetically engineered archaeon of the polypeptide during growth at a second temperature that is at or near the T.sub.opt of the genetically engineered archaeon.
