Abstract
The control of DNA topology is a prerequisite for all the DNA transactions such as DNA replication, repair, recombination, and transcription. This global control is carried out by essential enzymes, named DNA-topoisomerases, that are mandatory for the genome stability. Since many decades, the Archaea provide a significant panel of new types of topoisomerases such as the reverse gyrase, the type IIB or the type IC. These more or less recent discoveries largely contributed to change the understanding of the role of the DNA topoisomerases in all the living world. Despite their very different life styles, Archaea share a quasi-homogeneous set of DNA-topoisomerases, except thermophilic organisms that possess at least one reverse gyrase that is considered a marker of the thermophily. Here, we discuss the effect of the life style of Archaea on DNA structure and topology and then we review the content of these essential enzymes within all the archaeal diversity based on complete sequenced genomes available. Finally, we discuss their roles, in particular in the processes involved in both the archaeal adaptation and the preservation of the genome stability.

Abstract
Reverse gyrase (RG) is the only protein found ubiquitously in hyperthermophilic organisms, but absent from mesophiles. As such, its simple presence or absence allows us to deduce information about the optimal growth temperature of long-extinct organisms, even as far as the last universal common ancestor of extant life (LUCA). The growth environment and gene content of the LUCA has long been a source of debate in which RG often features. In an attempt to settle this debate, we carried out an exhaustive search for RG proteins, generating the largest RG data set to date. Comprising 376 sequences, our data set allows for phylogenetic reconstructions of RG with unprecedented size and detail. These RG phylogenies are strikingly different from those of universal proteins inferred to be present in the LUCA, even when using the same set of species. Unlike such proteins, RG does not form monophyletic archaeal and bacterial clades, suggesting RG emergence after the formation of these domains, and/or significant horizontal gene transfer. Additionally, the branch lengths separating archaeal and bacterial groups are very short, inconsistent with the tempo of evolution from the time of the LUCA. Despite this, phylogenies limited to archaeal RG resolve most archaeal phyla, suggesting predominantly vertical evolution since the time of the last archaeal ancestor. In contrast, bacterial RG indicates emergence after the last bacterial ancestor followed by significant horizontal transfer. Taken together, these results suggest a nonhyperthermophilic LUCA and bacterial ancestor, with hyperthermophily emerging early in the evolution of the archaeal and bacterial domains.

The reverse gyrase TopR1 is responsible for the homeostatic control of DNA supercoiling in the hyperthermophilic archaeon Sulfolobus solfataricus. Mol Microbiol 2019; 113:356-368.

Abstract
Maintaining an appropriate DNA topology with DNA-based processes (DNA replication, transcription and recombination) is crucial for all three domains of life. In bacteria, the homeostatic regulation for controlling DNA supercoiling relies on antagonistic activities of two DNA topoisomerases, TopoI and gyrase. In hyperthermophilic crenarchaea, the presence of such a regulatory system is suggested as two DNA topoisomerases, TopoVI and reverse gyrase, catalyze antagonistic activities. To test this hypothesis, we estimated and compared the number of the TopoVI with that of the two reverse gyrases, TopR1 and TopR2, in Sulfolobus solfataricus cells maintained either at 80 or at 88°C, or reciprocally shifted from one temperature to the other. From the three DNA topoisomerases, TopR1 is the only one exhibiting significant quantitative variations in response to the up- and down-shifts. In addition, the corresponding intrinsic activities of these three DNA topoisomerases were tested in vitro at both temperatures. Although temperature modulates the three DNA topoisomerases activities, TopR1 is the sole topoisomerase able to function at high temperature. Altogether, results presented in this study demonstrate, for the first time, that the DNA topological state of a crenarchaeon is regulated via a homeostatic control, which is mainly mediated by the fine-tuning of TopR1.

Abstract
DNA topoisomerases are essential enzymes involved in all the DNA processes and among them, type IA topoisomerases emerged as a key actor in the maintenance of genome stability. The hyperthermophilic archaeon, Sulfolobus solfataricus, contains three topoisomerases IA including one classical named TopA. SsoTopA is very efficient at unlinking DNA catenanes, grouping SsoTopA into the topoisomerase III family. SsoTopA is active over a wide range of temperatures and at temperatures of up to 85°C it produces highly unwound DNA. At higher temperatures, SsoTopA unlinks the two DNA strands. Thus depending on the temperature, SsoTopA is able to either prevent or favor DNA melting. While canonical topoisomerases III require a single-stranded DNA region or a nick in one of the circles to decatenate them, we show for the first time that a type I topoisomerase, SsoTopA, is able to efficiently unlink covalently closed catenanes, with no additional partners. By using single molecule experiments we demonstrate that SsoTopA requires the presence of a short single-stranded DNA region to be efficient. The unexpected decatenation property of SsoTopA probably comes from its high ability to capture this unwound region. This points out a possible role of TopA in S. solfataricus as a decatenase in Sulfolobus.

Abstract
All the type IA topoisomerases display universal characteristics relying on a core region basically responsible for the transesterification and the strand passage reaction. First limited to the bacterial domain for a long time, these enzymes were further retrieved in Archaea and Eukarya as well. This is representative of an extremely ancient origin, probably due to an inheritance from the RNA world. As remaining evidence, some current topoisomerases IA have retained a RNA topoisomerase activity. Despite the presence of this core region in all of these TopoIAs, some differences exist and are originated from variable regions, located essentially within both extremities, conferring on them their specificities. During the last 2 decades the evidence of multiple activities and dedicated roles highlighted the importance of the topoisomerases IA. It is now obvious that topoisomerases IA are key enzymes involved in the maintenance of the genome stability. The discovery of these new activities was done thanks to the use of more accurate assays, based on new sophisticated DNA substrates.

Abstract
Reverse gyrase introduces positive supercoils to circular DNA and is implicated in genome stability maintenance in thermophiles. The extremely thermophilic crenarchaeon Sulfolobus encodes two reverse gyrase proteins, TopR1 (topoisomerase reverse gyrase 1) and TopR2, whose functions in thermophilic life remain to be demonstrated. Here, we investigated the roles of TopR1 in genome stability maintenance in S. islandicus in response to the treatment of methyl methanesulfonate (MMS), a DNA alkylation agent. Lethal MMS treatment induced two successive events: massive chromosomal DNA backbone breakage and subsequent DNA degradation. The former occurred immediately after drug treatment, leading to chromosomal DNA degradation that concurred with TopR1 degradation, followed by chromatin protein degradation and DNA-less cell formation. To gain a further insight into TopR1 function, the expression of the enzyme was reduced in S. islandicus cells using a CRISPR-mediated mRNA interference approach (CRISPRi) in which topR1 mRNAs were targeted for degradation by endogenous III-B CRISPR-Cas systems. We found that the TopR1 level was reduced in the S. islandicus CRISPRi cells and that the cells underwent accelerated genomic DNA degradation during MMS treatment, accompanied by a higher rate of cell death. Taken together, these results indicate that TopR1 probably facilitates genome integrity maintenance by protecting DNA breaks from thermo-degradation in vivo.

Abstract
Reverse gyrase is an enzyme that can overwind (introduce positive supercoils into) DNA using the energy obtained from ATP hydrolysis. The enzyme is found in hyperthermophiles, and the overwinding reaction generally requires a temperature above 70 °C. In a previous study using microscopy, we have shown that 30 consecutive mismatched base pairs (a bubble) in DNA serve as a well-defined substrate site for reverse gyrase, warranting the processive overwinding activity down to 50 °C. Here, we inquire how multiple reverse gyrase molecules may collaborate with each other in overwinding one DNA molecule. We introduced one, two, or four bubbles in a linear DNA that tethered a magnetic bead to a coverslip surface. At 40-71 °C in the presence of reverse gyrase, the bead rotated clockwise as viewed from above, to relax the DNA twisted by reverse gyrase. Dependence on the enzyme concentration indicated that each bubble binds reverse gyrase tightly (dissociation constant < 0.1 nm) and that bound enzyme continuously overwinds DNA for > 5 min. Rotation with two bubbles was significantly faster compared with one bubble, indicating that overwinding actions are basically additive, but four bubbles did not show further acceleration except at 40 °C where the activity was very low. The apparent saturation is due to the hydrodynamic friction against the rotating bead, as confirmed by increasing the medium viscosity. When torsional stress in the DNA, determined by the friction, approaches ~ 7 pN·nm (at 71 °C), the overwinding activity of reverse gyrase drops sharply. Multiple molecules of reverse gyrase collaborate additively within this limit.
