Abstract:
Controlling the aggregation of vital bacterial proteins could be one of the new research directions and form the basis for the search and development of antibacterial drugs with targeted action. Such approach may be considered as an alternative one to antibiotics. Amyloidogenic regions can, like antibacterial peptides, interact with the “parent” protein, for example, ribosomal S1 protein (specific only for bacteria), and interfere with its functioning. The aim of the work was to search for peptides based on the ribosomal S1 protein from T. thermophilus, exhibiting both aggregation and antibact

Abstract:
ABSTRACT The extremely thermophilic bacterium Thermus thermophilus HB8, which belongs to the phylum Deinococcus-Thermus, has an open reading frame encoding a protein belonging to the cyclic AMP (cAMP) receptor protein (CRP) family present in many bacteria. The protein named T. thermophilus CRP is highly homologous to the CRP family proteins from the phyla Firmicutes, Actinobacteria, and Cyanobacteria, and it forms a homodimer and interacts with cAMP. CRP mRNA and intracellular cAMP were detected in this strain, which did not drastically fluctuate during cultivation in a rich medium. The expres

Abstract:
ABSTRACT Thermus thermophilus HB27, an extremely thermophilic bacterium, exhibits high competence for natural transformation. To identify genes of the natural transformation machinery of T. thermophilus HB27, we performed homology searches in the partially completed T. thermophilus genomic sequence for conserved competence genes. These analyses resulted in the detection of 28 open reading frames (ORFs) exhibiting significant similarities to known competence proteins of gram-negative and gram-positive bacteria. Disruption of 15 selected potential competence genes led to the identification of 8

Abstract:
Members of the Obg subfamily of small GTP-binding proteins (called Obg, CgtA, ObgE or YhbZ in different bacterial species) have been found in various prokaryotic and eukaryotic organisms, ranging from bacteria to humans. Although serious changes in phenotypes are observed in mutant bacteria devoid of Obg or its homologues, specific roles of these GTP-binding proteins remain largely unknown. Recent genetic and biochemical studies, as well as determination of the structures of Obg proteins from Bacillus subtilis and Thermus thermophilus, shed new light on the possible functions of the members of

Abstract:
ABSTRACT Proteins belonging to the Omp85 family are involved in the assembly of β-barrel outer membrane proteins or in the translocation of proteins across the outer membrane in bacteria, mitochondria, and chloroplasts. The cell envelope of the thermophilic bacterium Thermus thermophilus HB27 is multilayered, including an outer membrane that is not well characterized. Neither the precise lipid composition nor much about integral membrane proteins is known. The genome of HB27 encodes one Omp85-like protein, Omp85Tt, representing an ancestral type of this family. We overexpressed Omp85Tt in T. t

Abstract:
Phosphoserine phosphatase (PSP) catalyzes the dephosphorylation of phosphoserine to serine and inorganic phosphate. PSPs, which have been found in all three domains of life, belong to the haloacid dehalogenase-like hydrolase superfamily. However, certain organisms, particularly bacteria, lack a classical PSP gene, although they appear to possess a functional phosphoserine synthetic pathway. The apparent lack of a PSP ortholog in Hydrogenobacter thermophilus, an obligately chemolithoautotrophic and thermophilic bacterium, represented a missing link in serine anabolism because our previous study

Abstract:
Abstract A putative operon of the ribosomal proteins S20 and Thx has been determined in a 1.4 kb sequenced region of T. thermophilus genomic DNA. Both genes have a promoter sequence 29 nt upstream of ORF1, possess their own ShineDalgarno motifs (GGAG) and are separated by only 9 nucleotides, a feature characteristic of the compact Thermus thermophilus genome. This is a novel arrangement, since Thx is unique to the Thermus bacteria and in all other prokaryotes the S20 gene is monocistronic. Our results, in conjunction with the recent finding that Thx is located on the top of the head of the 30S

Tiamulin is a semisynthetic pleuromutilin antibiotic that binds to the 50S ribosomal subunit A site and whose (((2-diethylamino)ethyl)thio)-acetic acid tail extends into the P site to interfere with peptide bond formation. We have isolated spontaneous tiamulin-resistant mutants of the thermophilic bacterium Thermus thermophilus, containing either single amino acid substitutions in ribosomal protein uL3 or single base substitutions in the peptidyltransferase active site of 23S rRNA. These mutations are consistent with those found in other organisms and are in close proximity to the crystallogra

We have carried out structural studies on bovine pancreatic phospholipase A2 (BPLA2) and two proteins involved in molybdenum cofactor (Moco) biosynthesis pathway. In addition, molecular-dynamics simulations and other analyses have been performed to corroborate the findings obtained from the crystal structures. Crystal structures of the three active-site mutants (H48N, D49N and D49K) of BPLA2 were determined to understand the mechanism by which the mutant H48N is able to catalyze the reaction of phospholipid hydrolysis and to see the effect of the loss of Ca 2+ ion in the active site of D49N a
