dc.description.abstract | The PII proteins from the cyanobacteria Synechococcus sp.
PCC 7942 and Synechocystis sp. PCC 6803 have been
crystallized and high-resolution structures have been obtained
using X-ray crystallography. The core of these new structures
is similar to that of the PII proteins from Escherichia coli,
although the structures of the T- and C-loops differ. The
T-loop of the Synechococcus protein is ordered, but appears to
be stabilized by crystal contacts. The same loop in the
Synechocystis protein is disordered. The C-terminus of the
Synechocystis protein is stabilized by hydrogen bonding to the
same region of a crystallographically related molecule. The
same terminus in the Synechococcus protein is stabilized by
coordination with a metal ion. These observations are
consistent with the idea that both the T-loop and the
C-terminus of PII proteins are ¯exible in solution and that
this ¯exibility may be important for receptor recognition.
Sequence comparisons are used to identify regions of the
sequence unique to the cyanobacteria. | es |
