Crystallization and preliminary crystallographic studies of calgranulin C, an S100-like calcium-binding protein from pig granulocytes

Calgranulin C (CAGC) from pig granulocytes has been crystallized and X-ray diffraction data have been collected to 2.6 Å resolution. The crystals belong to the trigonal system, space group P3₁21 or P3₂21, cell parameters a = b = 54.35 (2), c = 141.32 (5) Å and probably contain two molecules in the asymmetric unit. CAGC is amongst the first reported typical S100-1ike calcium-binding protein to be crystallized and studied by X-ray crystallography.
