groEL expression in gyrB mutants of Borrelia burgdorferi.
GroEL protein and groEL mRNA transcript were up-regulated in gyrB mutants of Borrelia burgdorferi, a causative agent of Lyme disease. Furthermore, the protein and transcript levels in gyrB mutants were greater than those in experimentally heat-shocked cultures of wild-type B. burgdorferi. Circular DNA in the gyrB mutants was more relaxed than in wild-type cells, although groEL is on the linear ...
متن کاملExpression and Purification of Recombinant Outer Surface Protein D of Borrelia burgdorferi
To carry out the immunological experiments on the serum of Multiple Sclerosis (MS) patients, based on a correlation between Borrelia burgdorferi infection and contracting MS autoimmune disease the outer surface protein D (OspD) of the bacterium was expressed and purified. A clone containing the OspD gene in pET11a expression vector under the control of T7 promoter was transformed to the bacteri...
متن کاملAsymmetrical flagellar rotation in Borrelia burgdorferi nonchemotactic mutants.
The Lyme disease spirochete Borrelia burgdorferi has bundles of periplasmic flagella subpolarly located at each cell end. These bundles rotate in opposite directions during translational motility. When not translating, they rotate in the same direction, and the cells flex. Here, we present evidence that asymmetrical rotation of the bundles during translation does not depend upon the chemotaxis ...
متن کاملGenetic transformation of the Lyme disease agent Borrelia burgdorferi with coumarin-resistant gyrB.
No useful method to genetically manipulate Borrelia burgdorferi, the causative agent of Lyme disease, has been developed previously. We have used resistance to the coumarin antibiotic coumermycin A1, an inhibitor of DNA gyrase, as a genetic marker to monitor the transformation of B. burgdorferi by electroporation. Introduction of site-directed mutations into the gyrB gene demonstrated that tran...
متن کاملEvaluation of groEL gene analysis for identification of Borrelia burgdorferi sensu lato.
The nucleotide sequences of the groEL genes, the flagellin genes, and the 16S rRNA genes from 22 reference strains of Borrelia were compared. groEL sequence analysis is useful not only in interspecies differentiation but also in intraspecies differentiation of Borrelia afzelii and Borrelia garinii isolates.
