abstract = {The neutron single crystal diffractometer BIODIFF at the
research reactor Heinz Maier-Leibnitz (FRM II) is especially
designed to collect data from crystals with large unit
cells. The main field of application is the structural
analysis of proteins, especially the determination of
hydrogen atom positions. BIODIFF is a joint project of the
Jülich Centre for Neutron Science (JCNS) and the FRM II.
BIODIFF is designed as a monochromatic instrument with a
narrow wavelength spread of less than 3 $\%.$ To cover a
large solid angle the main detector of BIODIFF consists of a
neutron imaging plate in a cylindrical geometry with online
read-out capability. BIODFF is equipped with a standard
Oxford Cryosystem “Cryostream 700+” which allows
measurements at 100 K. A new kappa goniometer head was added
recently. This allows an automated tilting of the crystal in
order to increase the completeness of the data set when
recording another set of frames in the tilted geometry.
Typical scientific questions addressed are the determination
of protonation states of amino acid side chains in proteins
and the characterization of the hydrogen bonding networks
between the protein active centre and an inhibitor or
substrate. Picking out some recent highlights from
measurements at BIODIFF it will be shown how the method of
neutron protein crystallography could be used to answer
mechanistic questions in enzymatic processes or help to
improve inhibitor fragment screening.},
