NMR spectroscopy again confirmed that the structures of the wild type and mutants are not significantly affected by the deletions (Supplementary Fig. 9b). The effect of deleting loop-4 is particularly interesting as the equivalent region of KdHpuA, albeit being three residues shorter, is not ...

Further, in the present specification, “1H-NMR (CDCl3)” represents δ (ppm) of a peak in 1H-NMR in deuterochloroform, “1H-NMR (DMSO-d6)” represents δ (ppm) of a peak in 1H-NMR in dimethylsulfoxide-d6,“EI” represents EI-MS [M]+,“FAB+” represents FAB-MS [M+H]+,“...
NMRMicrostructureIn order to optimize hydrogen storage properties of bcc Ti-V-Cr alloys it was found that alloying with a few 4 at% of Zr7Ni10 results in acceleration the hydrogen sorption kinetics in the composite material. The novel intergranular phase plays a role of gate for hydrogen, ...
a, 1H NMR spectra of DMPESI in anhydrous DMSO-d6 after six months of storage in ambient air. The H2O peak in DMSO-d6 is at 3.3 ppm (vertical dashed blue line): the signal is absent in the samples. The chemical structure of DMPESI is shown. b, Photographs of fresh and 24-mon...
2.2.2. H-NMR Analysis 1H NMR (400 MHz) spectra were carried out (Bruker, Munich, Germany) using tetramethylsilane TMS as internal standard and dimethyl sulfoxide (DMSO-d6) as a solvent. Chemical shift values are reported in ppm. Elemental analyses were performed at the Microanalytical Unit,...
