Transcription termination factor Rho is essential for Micrococcus luteus.

ABSTRACT: The growth of Micrococcus luteus, a soil microorganism that belongs to the high-G+C gram-positive phylogenetic group, is prevented by bicyclomycin, an antibiotic that inhibits the activity of the M. luteus transcription termination factor Rho. A mutant that can grow in 0.3 mM bicyclomycin has a Rho that is insensitive to bicyclomycin and has the single amino acid residue change of Asp474 to Gly. These results indicate that the function of its Rho factor is essential for M. luteus and that growth of a gram-positive organism can be blocked by bicyclomycin.

Diversification of the Rho transcription termination factor in bacteria.

Project description:Correct termination of transcription is essential for gene expression. In bacteria, factor-dependent termination relies on the Rho factor, that classically has three conserved domains. Some bacteria also have a functional insertion region. However, the variation in Rho structure among bacteria has not been analyzed in detail. This study determines the distribution, sequence conservation, and predicted features of Rho factors with diverse domain architectures by analyzing 2730 bacterial genomes. About half (49.8%) of the species analyzed have the typical Escherichia coli like Rho while most of the other species (39.8%) have diverse, atypical forms of Rho. Besides conservation of the main domains, we describe a duplicated RNA-binding domain present in specific species and novel variations in the bicyclomycin binding pocket. The additional regions observed in Rho proteins exhibit remarkable diversity. Commonly, however, they have exceptional amino acid compositions and are predicted to be intrinsically disordered, to undergo phase separation, or have prion-like behavior. Phase separation has recently been shown to play roles in Rho function and bacterial fitness during harsh conditions in one species and this study suggests a more widespread role. In conclusion, diverse atypical Rho factors are broadly distributed among bacteria, suggesting additional cellular roles.

Crystal structure of the Escherichia coli transcription termination factor Rho.

Project description:During the crystal structure analysis of an ATP-binding cassette (ABC) transporter overexpressed in Escherichia coli, a contaminant protein was crystallized. The identity of the contaminant was revealed by mass spectrometry to be the Escherichia coli transcription terminator factor Rho, structures of which had been previously determined in different conformational states. Although Rho was present at only ∼1% of the target protein (a bacterial homolog of the eukaryotic ABC transporter of mitochondria from Novosphingobium aromaticivorans; NaAtm1), it preferentially crystallized in space group C2 as thin plates that diffracted to 3.30 Å resolution. The structure of Rho in this crystal form exhibits a hexameric open-ring staircase conformation with bound ATP; this characteristic structure was also observed on electron-microscopy grids of the NaAtm1 preparation.

Keeping up to speed with the transcription termination factor Rho motor.

Project description:In bacteria, a subset of transcription termination events requires the participation of the transcription termination factor Rho. Rho is a homo-hexameric, ring-shaped, motor protein that uses the energy derived from its RNA-dependent ATPase activity to directionally unwind RNA and RNA-DNA helices and to dissociate transcription elongation complexes. Despite a wealth of structural, biochemical and genetic data, the molecular mechanisms used by Rho to carry out its biological functions remain poorly understood. Here, we briefly discuss the most recent findings on Rho mechanisms and function and highlight important questions that remain to be addressed.

Direct observation of the translocation mechanism of transcription termination factor Rho.

Project description:Rho is a ring-shaped, ATP-fueled motor essential for remodeling transcriptional complexes and R-loops in bacteria. Despite years of research on this fundamental model helicase, key aspects of its mechanism of translocation remain largely unknown. Here, we used single-molecule manipulation and fluorescence methods to directly monitor the dynamics of RNA translocation by Rho. We show that the efficiency of Rho activation is strongly dependent on the force applied on the RNA but that, once active, Rho is able to translocate against a large opposing force (at least 7 pN) by a mechanism involving 'tethered tracking'. Importantly, the ability to directly measure dynamics at the single-molecule level allowed us to determine essential motor properties of Rho. Hence, Rho translocates at a rate of ?56 nt per second under our experimental conditions, which is 2-5 times faster than velocities measured for RNA polymerase under similar conditions. Moreover, the processivity of Rho (?62 nt at a 7 pN opposing force) is large enough for Rho to reach termination sites without dissociating from its RNA loading site, potentially increasing the efficiency of transcription termination. Our findings unambiguously establish 'tethered tracking' as the main pathway for Rho translocation, support 'kinetic coupling' between Rho and RNA polymerase during Rho-dependent termination, and suggest that forces applied on the nascent RNA transcript by cellular substructures could have important implications for the regulation of transcription and its coupling to translation in vivo.

Depleting Mycobacterium tuberculosis of the transcription termination factor Rho causes pervasive transcription and rapid death.

Project description:Rifampicin, which inhibits bacterial RNA polymerase, provides one of the most effective treatments for tuberculosis. Inhibition of the transcription termination factor Rho is used to treat some bacterial infections, but its importance varies across bacteria. Here we show that Rho of Mycobacterium tuberculosis functions to both define the 3' ends of mRNAs and silence substantial fragments of the genome. Brief inactivation of Rho affects over 500 transcripts enriched for genes of foreign DNA elements and bacterial virulence factors. Prolonged inactivation of Rho causes extensive pervasive transcription, a genome-wide increase in antisense transcripts, and a rapid loss of viability of replicating and non-replicating M. tuberculosis in vitro and during acute and chronic infection in mice. Collectively, these data suggest that inhibition of Rho may provide an alternative strategy to treat tuberculosis with an efficacy similar to inhibition of RNA polymerase.

ATP-dependent motor activity of the transcription termination factor Rho from Mycobacterium tuberculosis.

Project description:The bacterial transcription termination factor Rho-a ring-shaped molecular motor displaying directional, ATP-dependent RNA helicase/translocase activity-is an interesting therapeutic target. Recently, Rho from Mycobacterium tuberculosis (MtbRho) has been proposed to operate by a mechanism uncoupled from molecular motor action, suggesting that the manner used by Rho to dissociate transcriptional complexes is not conserved throughout the bacterial kingdom. Here, however, we demonstrate that MtbRho is a bona fide molecular motor and directional helicase which requires a catalytic site competent for ATP hydrolysis to disrupt RNA duplexes or transcription elongation complexes. Moreover, we show that idiosyncratic features of the MtbRho enzyme are conferred by a large, hydrophilic insertion in its N-terminal 'RNA binding' domain and by a non-canonical R-loop residue in its C-terminal 'motor' domain. We also show that the 'motor' domain of MtbRho has a low apparent affinity for the Rho inhibitor bicyclomycin, thereby contributing to explain why M. tuberculosis is resistant to this drug. Overall, our findings support that, in spite of adjustments of the Rho motor to specific traits of its hosting bacterium, the basic principles of Rho action are conserved across species and could thus constitute pertinent screening criteria in high-throughput searches of new Rho inhibitors.

The Bacterial Transcription Termination Factor Rho Coordinates Mg(2+) Homeostasis with Translational Signals.

Project description:The bacterial protein Rho triggers transcription termination at the ends of many operons and when transcription and translation become uncoupled. In addition to these genome wide activities, Rho implements regulation of specific genes by dictating whether RNA polymerase terminates transcription within the 5' leader region or continues into the downstream coding region. Here, we report that the Mg(2+) channel gene corA in Salmonella enterica serovar Typhimurium, which was previously thought to be constitutively expressed, is regulated by a Rho-dependent terminator located within its 5' leader region. We demonstrate that the unusually long and highly conserved corA leader mRNA can adopt two mutually exclusive conformations that determine whether or not Rho interacts with a Rho utilization site on the nascent RNA and thereby prevents transcription of the corA coding region. The RNA conformation that promotes Rho-dependent termination is favored by efficient translation of corL, a short open reading frame located within the corA leader. Thus, corA transcription is inversely coupled to corL translation. This mechanism resembles those governing expression of Salmonella's other two Mg(2+) transport genes, suggesting that Rho links Mg(2+) uptake to translational signals.

Riboswitch control of Rho-dependent transcription termination.

Project description:Riboswitches are RNA sensors that regulate gene expression upon binding specific metabolites or ions. Bacterial riboswitches control gene expression primarily by promoting intrinsic transcription termination or by inhibiting translation initiation. We now report a third general mechanism of riboswitch action: governing the ability of the RNA-dependent helicase Rho to terminate transcription. We establish that Rho promotes transcription termination in the Mg(2+)-sensing mgtA riboswitch from Salmonella enterica serovar Typhimurium and the flavin mononucleotide-sensing ribB riboswitch from Escherichia coli when the corresponding riboswitch ligands are present. The Rho-specific inhibitor bicyclomycin enabled transcription of the coding regions at these two loci in bacteria experiencing repressing concentrations of the riboswitch ligands in vivo. A mutation in the mgtA leader that favors the "high Mg(2+)" conformation of the riboswitch promoted Rho-dependent transcription termination in vivo and in vitro and enhanced the ability of the RNA to stimulate Rho's ATPase activity in vitro. These effects were overcome by mutations in a C-rich region of the mRNA that is alternately folded at high and low Mg(2+), suggesting a role for this region in regulating the activity of Rho. Our results reveal a potentially widespread mode of gene regulation whereby riboswitches dictate whether a protein effector can interact with the transcription machinery to prematurely terminate transcription.

Rho-dependent transcription termination: a revisionist view.

Project description:Rho is a hexameric bacterial RNA helicase, which became a paradigm of factor-dependent transcription termination. The broadly accepted ("textbook") model posits a series of steps, wherein Rho first binds C-rich Rho utilization (rut) sites on nascent RNA, uses its ATP-dependent translocase activity to catch up with RNA polymerase (RNAP), and either pulls the transcript from the elongation complex or pushes RNAP forward, thus terminating transcription. However, this appealingly simple mechano-chemical model lacks a biological realism and is increasingly at odds with genetic and biochemical data. Here, we summarize recent structural and biochemical studies that have advanced our understanding of molecular details of RNA recognition, termination signaling, and RNAP inactivation in Rho-dependent transcription termination, rebalancing the view in favor of an alternative "allosteric" mechanism. In the revised model, Rho binds RNAP early in elongation assisted by the cofactors NusA and NusG, forming a pre-termination complex (PTC). The formation of PTC allows Rho to continuously sample nascent transcripts for a termination signal, which subsequently traps the elongation complex in an inactive state prior to its dissociation.
