CMT disease severity correlates with mutation-induced open conformation of histidyl-tRNA synthetase, not aminoacylation loss, in patient cells
09 September 2019
In the recent issue of PNAS, researchers from The Scripps Research Institute present their latest groundbreaking findings on the neurodegenerative Charcot-Marie-Tooth (CMT) disease. The study demonstrates that the severity of the CMT disease is closely linked to distinct mutations in the histidyl-tRNA synthetase protein.
Using the switchSENSE® technology, the Scripps researchers could measure the variable mutation-induced conformational expansion of the mutated synthetases in comparison to the wild-type protein. Small-angle X-ray scattering (SAXS) and hydrogen/deuterium (HDX) analyses confirmed the switchSENSE® results. These structural and size measurements enabled the ranking of the different mutations, stating a strong correlation with the severity of the CMT disease.

Triazine-Modified 7-Deaza-2′-deoxyadenosines: Better Suited for Bioorthogonal Labeling of DNA by PCR than 2′-Deoxyuridines
22 May 2019
Researchers from the Karlsruhe Institute of Technology attached the bioorthogonally reactive 6-Ethynyl-1,2,4-triazine grou to the 7-position of 7-deaza-2-deoxyadenosine triphosphate and to the 5-position of 2-deoxyuridine triphosphate for subsequent labelling. Both, Primer extension experiments (PEX) and PCR amplification, show that 6-ethynyl-1,2,4-triazine is much better tolerated by the DNA polymerase when attached to the 7-position of 7-deaza-2-deoxyadenosine in comparison to the attachment at the 5-position of 2-deoxyuridine. Real-time kinetic observation of DNA polymerase activity during primer extension using switchSENSE® clearly shows this behavior and imply that bioorthogonal labeling strategies are better suited for 7-deaza-2-adenosines than conventional and available 2-deoxyuridines.
