Fricke, P., et al., Studies on the MxiH protein in T3SS needles using DNP-enhanced ssNMR spectroscopy. ChemPhysChem, 2014. 15(1): p. 57-60.
Bacterial T3SS needles formed by the protein MxiH are studied using DNP-enhanced ssNMR spectroscopy at 14.1 T (600 MHz). This technique provides spectra of good resolution, allowing us to draw conclusions about the protein dynamics. With the obtained signal enhancement, samples of limited quantity now get within reach of ssNMR studies.
