Abstract:
Two different crystal forms of human C-reactive protein have been grown from solutions of 2-methyl-2,4-pentanediol. Both crystal forms are tetragonal, the space group for form I is P4(1)22 (or P4(3)22), and that for form II is P4(2)22. The unit cell parameters for form I are a = b = 103.0(5) A, c = 308.5(7) A and for form II are a = b = 103.1(2) A, c = 312.7(6) A. The crystals of form II diffract to at least 3.0 A resolution, and are suitable for detailed structural studies.
