Resistance of Thermus spp. to Potassium Tellurite.
نویسندگان
چکیده
Two members of the genus Thermus were examined for their resistance to toxic inorganic compounds. They both proved to be fairly resistant to tellurite and selenite and to many other heavy metal salts. Cell extracts of Thermus thermophilus HB8 and of T. flavus AT-62 catalyze the reduction of K(2)TeO(3) in a reaction which is dependent on NADH oxidation.

Purification and biochemical characterization of tellurite-reducing activities from Thermus thermophilus HB8.
Cell-free extracts of Thermus thermophilus HB8 catalyze the in vitro, NADH-dependent reduction of potassium tellurite (K2TeO3). Three different protein fractions with tellurite-reducing activities were identified. Two exhibited high molecular weight and were composed of at least two different polypeptides. The protein in the third fraction was purified to homogeneity and had a single polypeptid...
متن کاملThe Geobacillus stearothermophilus V iscS gene, encoding cysteine desulfurase, confers resistance to potassium tellurite in Escherichia coli K-12.
Many eubacteria are resistant to the toxic oxidizing agent potassium tellurite, and tellurite resistance involves diverse biochemical mechanisms. Expression of the iscS gene from Geobacillus stearothermophilus V, which is naturally resistant to tellurite, confers tellurite resistance in Escherichia coli K-12, which is naturally sensitive to tellurite. The G. stearothermophilus iscS gene encodes...
متن کاملThe tellurite-resistance determinants tehAtehB and klaAklaBtelB have different biochemical requirements.
The tehAtehB operon from the Escherichia coli chromosome (32.3 min) mediates resistance to potassium tellurite (K2TeO3) when expressed on a multicopy plasmid such as pUC8 (pTWT100). An MIC of 128 micrograms ml-1 is observed when tehAtehB is expressed in a wild-type host and grown on rich media. In this study, the tehAtehB determinant was transformed into mutants deficient in electron transport ...
متن کاملTellurite reductase activity of nitrate reductase is responsible for the basal resistance of Escherichia coli to tellurite.
Tellurite and selenate reductase activities were identified in extracts of Escherichia coli. These activities were detected on non-denaturing polyacrylamide gels using an in situ methyl viologen activity-staining technique. The activity bands produced from membrane-protein extracts had the same RF values as those of nitrate reductases (NRs) A and Z. Tellurite and selenate reductase activities w...
متن کاملUse of tellurite for the selection of verocytotoxigenic Escherichia coli O157.
Potassium tellurite was assessed for the selection of verocytotoxigenic (VT+) Escherichia coli O157. MICs were higher for VT+ E. coli O157 than for other strains of E. coli and for Aeromonas spp. MacConkey medium containing sorbitol, tellurite and cefixime (TC-SMAC) permitted the growth of VT+ E. coli O157 and Shigella sonnei but partially or completely inhibited the growth of 67% of other stra...
