H-start for exclusively heteronuclear NMR spectroscopy: the case of intrinsically disordered proteins
Abstract
Here, we present a series of exclusively heteronuclear multidimensional NMR experiments, based on 13C direct detection, which exploit the (1)H polarization as a starting source to increase the signal-to-noise ratio. This contributes to make this spectroscopy more useful and usable. Examples are reported for a suitable system such as securin, an intrinsically disordered protein of 22 kDa.
