ABSTRACT
|
|
|
| |
|
Several crystal structures of parvalbumin (Parv), a typical EF-hand protein,
have been reported so far for different species with the best resolution
achieving 1.5 A. Using a crystal grown under microgravity conditions,
cryotechniques (100 K), and synchrotron radiation, it has now been possible to
determine the crystal structure of the fully Ca2+-loaded form of pike (component
pI 4.10) Parv.Ca2 at atomic resolution (0.91 A). The availability of such a high
quality structure offers the opportunity to contribute to the definition of the
validation tools useful for the refinement of protein crystal structures
determined to lower resolution. Besides a better definition of most of the
elements in the protein three-dimensional structure than in previous studies,
the high accuracy thus achieved allows the detection of well-defined alternate
conformations, which are observed for 16 residues out of 107 in total. Among
them, six occupy an internal position within the hydrophobic core and converge
toward two small buried cavities with a total volume of about 60 A3. There is no
indication of any water molecule present in these cavities. It is probable that
at temperatures of physiological conditions there is a dynamic interconversion
between these alternate conformations in an energy-barrier dependent manner.
Such motions for which the amplitudes are provided by the present study will be
associated with a time-dependent remodeling of the void internal space as part
of a slow dynamics regime (millisecond timescales) of the parvalbumin molecule.
The relevance of such internal dynamics to function is discussed.

The most recent references are shown first.
Citation data come partly from CiteXplore and partly
from an automated harvesting procedure. Note that this is likely to be
only a partial list as not all journals are covered by
either method. However, we are continually building up the citation data
so more and more references will be included with time.
