Title: SolidState NMR signal enhancement via DNP from endogenous flavin'


1
Solid-State NMR signal enhancement via DNP from
endogenous flavin.
Flavin in flavodoxin protein
Pulse sequence used for SS-NMR experiment with DNP
9-fold signal enhancement obtained, corresponding
to 25-fold enhancement possible at infinite
power.
Dipolar interaction between electron spins of
flavin semiquinone couple to nuclei nearby.
Irradiation of electron spins permits transfer
of polarization to nuclei, and observation of NMR
spectra with the signal strength of ESR.
SS-NMR enhancement with DNP
Production of flavin semiquinone
Semiquinone
Oxidized
