Compression of Large Sets of Sequence Data Reveals Fine Diversification of Functional Profiles in Multigene Families of Proteins
Technical note Compression of Large Sets of Sequence Data Reveals Fine Diversification of Functional Profiles in Multigene Families of Proteins: A Study for Peptidyl-Prolyl cis/trans Isomerases (PPIase) Andrzej Galat Retired from: Service d’Ingénierie Moléculaire des Protéines (SIMOPRO), CEA-Université Paris-Saclay, France; [email protected]; Tel.: +33-0164465072 Received: 21 December 2018; Accepted: 21 January 2019; Published: 11 February 2019 Abstract: In this technical note, we describe analyses of more than 15,000 sequences of FK506- binding proteins (FKBP) and cyclophilins, also known as peptidyl-prolyl cis/trans isomerases (PPIases). We have developed a novel way of displaying relative changes of amino acid (AA)- residues at a given sequence position by using heat-maps. This type of representation allows simultaneous estimation of conservation level in a given sequence position in the entire group of functionally-related paralogues (multigene family of proteins). We have also proposed that at least two FKBPs, namely FKBP36, encoded by the Fkbp6 gene and FKBP51, encoded by the Fkbp5 gene, can form dimers bound via a disulfide bridge in the nucleus. This type of dimer may have some crucial function in the regulation of some nuclear complexes at different stages of the cell cycle. Keywords: FKBP; cyclophilin; PPIase; heat-map; immunophilin 1 Introduction About 30 years ago, an exciting adventure began in finding some correlations between pharmacological activities of macrocyclic hydrophobic drugs, namely the cyclic peptide cyclosporine A (CsA), and two macrolides, namely FK506 and rapamycin, which have profound and clinically useful immunosuppressive effects, especially in organ transplantations and in combating some immune disorders. -

Courtney, Trevor J. Horst, Chasity P. Hankinson, and Alexander Deiters* Department of Chemistry, University of Pittsburgh, Pittsburgh, PA 15260, United States [email protected] Abstract: Rapamycin-induced dimerization of FKBP and FRB has been utilized as a tool for co-localizing two proteins of interest in numerous applications. Due to the tight binding interaction of rapamycin with FKBP and FRB, the ternary complex formation is essentially irreversible. Since biological processes occur in a highly dynamic fashion with cycles of protein association and dissociation to generate a cellular response, it is useful to have chemical tools that function in a similar manner. We have developed arylazopyrazole-modified rapamycin analogs which undergo a configurational change upon light exposure and we observed enhanced ternary complex formation for the cis-isomer over the trans-isomer for one of the analogs. Introduction: Chemical inducers of dimerization (CIDs) are prominent tools used by chemical biologists to place biological processes under conditional control.1-4 The most commonly utilized CID is rapamycin, a natural product that binds to FK506 binding protein (FKBP) with a 0.2 nM Kd. -

The immunosuppressant actions of these drugs occur through binding of cyclophilin-cyclosporinA and FK506 binding protein-FK506 complexes to the calcium-calmodulin-dependent protein phosphatase, calcineurin, inhibiting phosphatase activity, Utilizing immunohistcchemistry, in situ hybridization and autoradiography, we have localized protein and messenger RNA for FKS06 binding protein, cyclophilin and calcineurin. All three proteins and/or messages exhibit a heterogenous distribution through the brain and spinal cord, with the majority of the localizations being neuronal.

Protein sequence analysis revealed that the cold- adapted Ph DNA ligase shows a significant level of sequence similarity to other NAD1-dependent DNA ligases and contains several previously described sequence motifs. Also, a decreased level of arginine and proline residues in Ph DNA ligase could be involved in the cold-adaptation strategy. Moreover, 3D modelling of the N-terminal domain of Ph DNA ligase clearly indicates that this domain is destabilized compared with its thermophilic homologue. The recombinant Ph DNA ligase was overexpressed in Escherichia coli and purified to homogeneity. Mass spectroscopy experiments indicated that the purified enzyme is mainly in an adenylated form with a molecular mass of 74 593 Da. Ph DNA ligase shows similar overall catalytic properties to other NAD1-dependent DNA ligases but is a cold-adapted enzyme as its catalytic efficiency (kcat/Km) at low and moderate temperatures is higher than that of its mesophilic counterpart E. -

Advanced Review Physiological, metabolic and biotechnological features of extremely thermophilic microorganisms James A. Counts,1 Benjamin M. Zeldes,1 Laura L. Lee,1 Christopher T. Straub,1 Michael W.W. Adams2 and Robert M. Kelly1* The current upper thermal limit for life as we know it is approximately 120C. Microorganisms that grow optimally at temperatures of 75C and above are usu- ally referred to as ‘extreme thermophiles’ and include both bacteria and archaea. For over a century, there has been great scientific curiosity in the basic tenets that support life in thermal biotopes on earth and potentially on other solar bodies. Extreme thermophiles can be aerobes, anaerobes, autotrophs, hetero- trophs, or chemolithotrophs, and are found in diverse environments including shallow marine fissures, deep sea hydrothermal vents, terrestrial hot springs— basically, anywhere there is hot water. Initial efforts to study extreme thermo- philes faced challenges with their isolation from difficult to access locales, pro- blems with their cultivation in laboratories, and lack of molecular tools. Fortunately, because of their relatively small genomes, many extreme thermo- philes were among the first organisms to be sequenced, thereby opening up the application of systems biology-based methods to probe their unique physiologi- cal, metabolic and biotechnological features. The bacterial genera Caldicellulosir- uptor, Thermotoga and Thermus, and the archaea belonging to the orders Thermococcales and Sulfolobales, are among the most studied extreme thermo- philes to date. The recent emergence of genetic tools for many of these organ- isms provides the opportunity to move beyond basic discovery and manipulation to biotechnologically relevant applications of metabolic engineering. -

Received: 5 June 2019; Accepted: 15 July 2019; Published: 18 July 2019 Abstract: Bacteria that thrive in extreme conditions and the bacteriophages that infect them are sources of valuable enzymes resistant to denaturation at high temperatures. Many of these heat-stable proteins are useful for biotechnological applications; nevertheless, none have been utilized as antibacterial agents. Here, we demonstrate the bactericidal potential of Ts2631 endolysin from the extremophilic bacteriophage vB_Tsc2631, which infects Thermus scotoductus, against the alarming multidrug-resistant clinical strains of Acinetobacter baumannii, Pseudomonas aeruginosa and pathogens from the Enterobacteriaceae family. A 2–3.7 log reduction in the bacterial load was observed in antibacterial tests against A. baumannii and P. aeruginosa after 1.5 h. The Ts2631 activity was further enhanced by ethylenediaminetetraacetic acid (EDTA), a metal ion chelator (4.2 log reduction in carbapenem-resistant A. baumannii) and, to a lesser extent, by malic acid and citric acid (2.9 and 3.3 log reductions, respectively). -

BIOGEOCHEMICAL INTERACTIONS IN FLOODED UNDERGROUND MINES by Renée Schmidt A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Geoscience: Geochemistry Option Montana Tech 2017 ii Abstract This study presents a biogeochemical analysis of microbial communities in flooded underground mines in Butte, Montana, USA. Samples were collected from nine mineshafts representing three distinct geochemical zones. These zones consist of the East, West, and Outer Camp mines. The East Camp mines, bordering the Berkeley Pit Superfund site, have the highest concentrations of dissolved metals and the most acidic pH values. Dissolved metal concentrations in the West Camp are one to three orders of magnitude lower than in the East Camp and have nearly neutral pH values. The Outer Camp mines have similar metal concentrations to the West Camp but are neutral to alkaline in pH. Sulfide levels also differ between the zones. In the East Camp, sulfide levels were below detection limits, whereas the West and Outer Camp mines had sulfide -6 -4 18 concentrations ranging from 10 to 10 mol/L. -
