Thermus thermophilus genome analysis: benefits and implications
The genome sequence analysis of Thermus thermophilus HB27, a microorganism with high biotechnological potential, has recently been published. In that report, the chromosomal and the megaplasmid sequence were compared to those of other organisms and discussed on the basis of their physiological and metabolic features. Out of the 2,218 putative genes identified through the large genome sequencing...
متن کاملGenome Signature Difference between Deinococcus radiodurans and Thermus thermophilus
The extremely radioresistant bacteria of the genus Deinococcus and the extremely thermophilic bacteria of the genus Thermus belong to a common taxonomic group. Considering the distinct living environments of Deinococcus and Thermus, different genes would have been acquired through horizontal gene transfer after their divergence from a common ancestor. Their guanine-cytosine (GC) contents are si...
متن کاملEngineering the substrate specificity of a thermophilic penicillin acylase from thermus thermophilus.
A homologue of the Escherichia coli penicillin acylase is encoded in the genomes of several thermophiles, including in different Thermus thermophilus strains. Although the natural substrate of this enzyme is not known, this acylase shows a marked preference for penicillin K over penicillin G. Three-dimensional models were created in which the catalytic residues and the substrate binding pocket ...
متن کاملRational engineering of Thermus thermophilus cytochrome c552 to a thermally tolerant artificial peroxidase.
In a previous study, we constructed a prototype thermally tolerant artificial peroxidase from an electron transfer protein, cytochrome c(552) from Thermus thermophilus, and demonstrated that engineering of proteins from thermophiles could be a promising methodology to produce artificial enzymes for practical use. In the present study, further improvement of the prototype (the V49D/M69A mutant) ...
متن کاملThermoadaptation of -Galactosidase AgaB1 in Thermus thermophilus
The evolutionary potential of a thermostable -galactosidase, with regard to improved catalytic activity at high temperatures, was investigated by employing an in vivo selection system based on thermophilic bacteria. For this purpose, hybrid -galactosidase genes of agaA and agaB from Bacillus stearothermophilus KVE39, designated agaA1 and agaB1, were cloned into an autonomously replicating Therm...
