Abstract
|
|
|
A new crystal form of pike (pI 4.10) parvalbumin has been crystallized in
presence of EDTA at pH 8.0. The crystals are orthorhombic, space group
P2(1)2(1)2(1), with a = 51.84, b = 49.95, c = 34.96 A. Diffractometer data were
collected to 1.75 A. The structure was solved by molecular replacement and
in the range
8.0-1.75 A. In spite of the presence of EDTA, calcium ions are present in both
primary binding sites. As compared to the previously reported structures, the
main differences concern the conformation of the N-terminal residues and the
packing in the unit cell.
