摘要:
Crystals of C-reactive protein from rat have been grown both with and without calcium. Two major components of the protein have been resolved on the basis of their calcium-dependent fine specificity for monophosphate esters. Crystals grown without calcium are tetragonal, space group P4212 with unit cell parameters a = b = 163.81(9)å and c = 125.21(6)å, and diffract X-rays to 3.0 å resolution. The rotation function specifies a molecular 5-fold symmetry axis at 24° away from c in the (110) plane. © 1994 Academic Press Limited.
