Although mycobacteria are known to accumulate polyphosphate (PolyP), a linear polymer of orthophosphate, when subjected to stresses, the exact roles of this molecule are not yet clearly understood. We found that deletion of the pstA gene encoding for a tra ...
Free extracellular DNA is abundant in many aquatic environments. While much of this DNA will be degraded by nucleases secreted by the surrounding microbial community, some is available as transforming material that can be taken up by naturally competent ba ...
The presence of a 174 kb plasmid called pMUM001 in Mycobacterium ulcerans, the first example of a mycobacterial plasmid encoding a virulence determinant, was recently reported. Over half of pMUM001 is devoted to six genes, three of which encode giant polyk ...
Desulfitobacterium hafniense strain TCE1 is capable of metabolically reducing tetra- and trichloroethenes by organohalide respiration. A previous study revealed that the pce gene cluster responsible for this process is located on an active composite transp ...
The organization of lin genes and IS6100 was studied in three strains of Sphingomonas paucimobilis (1390A, Sp+, and UT26) which degraded hexachlorocyclohexane (HCH) isomers but which had been isolated at different geographical locations. DNA-DNA hybridizat ...
Hyaline fibromatosis syndrome is an autosomal recessive disease caused by mutations in ANTXR2, a gene involved in extracellular matrix homeostasis. Sixty percent of patients carry frameshift mutations at a mutational hotspot in exon 13. We show in patient ...
L. monocytogenes is a Gram-positive intracellular pathogen that can cause serious disease, like septicemia and meningitis. It is detected in the cytosol by the innate immune system by sensing pathogen ligands. c-di-AMP has recently been shown to be one of ...
The insertion of peptide loops into the polypeptide chain of proteins at surface-exposed regions is an attractive avenue to modify the protein's properties or to evolve new functionalities. The strategy of peptide loop insertion has, for example, been used ...
The goal is to develop a miniaturized system allowing continuous measurement of glucose concentration profiles over 24 hours for several days. The unique feature of the PharmaSens / IMT approach lies in the insertion mechanism and the needle size to assure ...
Mycobacterium ulcerans causes the devastating infectious skin disease Buruli ulcer and has a monomorphic population structure. The resolution of conventional genetic fingerprinting methods is therefore not sufficient for microepidemiological studies aiming ...
