The format of this Chapter will be slightly different from that for earlier years.
Papers dealing with essentially static situations will be dealt with first – with
each Group of the Periodic Table discussed in turn. Results on dynamic
systems will then follow – again on the basis of the Periodic Groups, with
papers on paramagnetic compounds being dealt with last.
(BQ) Part 2 book "A complete introduction to modern NMR spectroscopy" has contents: The study of dynamic processes by NMR; electron paramagnetic resonance spectroscopy and chemically induced dynamic nuclear polarization; double resonance techniques and complex pulse sequences, two-dimensional nuclear magnetic resonance, NMR studies of biological important molecules,...and other contents.
Ech hydrogenase fromMethanosarcina barkeriis a member of a distinct
group of membrane-bound [NiFe] hydrogenases with sequence similarity
to energy-conserving NADH:quinone oxidoreductase (complex I). The
sequence of the enzyme predicts the binding of three [4Fe-4S] clusters, one
by subunit EchC and two by subunit EchF. Previous studies had shown
that two of these clusters could be fully reduced under 10
Pa of H2at pH
7 giving rise to two distinct S½ electron paramagnetic resonance (EPR)
signals, designated as the g¼1.89 and theg¼1.92 signal....
