abstract = {A growing number of nuclear magnetic resonance (NMR)
spectroscopic studies are impaired by the limited
information content provided by the standard set of
experiments conventionally recorded. This is particularly
true for studies of challenging biological systems including
large, unstructured, membrane-embedded and/or paramagnetic
proteins. Here we introduce the concept of unified
time-optimized interleaved acquisition NMR (UTOPIANMR) for
the unified acquisition of standard high-c (e.g. 1H) and
low-c (e.g. 13C) detected experiments using a single
receiver. Our aim is to activate the high level of
polarization and information content distributed on low-c
nuclei without disturbing conventional magnetization
transfer pathways. We show that using UTOPIA-NMR we are able
to recover nearly all of the normally non-used magnetization
without disturbing the standard experiments. In other words,
additional spectra, that can significantly increase the NMR
insights, are obtained for free. While we anticipate a broad
range of possible applications we demonstrate for the
soluble protein Bcl-xL (ca. 21 kDa) and for OmpX in
nanodiscs (ca. 160 kDa) that UTOPIA-NMR is particularly
useful for challenging protein systems including
perdeuterated (membrane) proteins.},
