Abstract: A novel trypsin inhibitor isolated from seeds of Copaifera langsdorffii was purified to homogeneity and crystallized. Crystals suitable for X-ray analysis were grown using the hanging-drop vapour-diffusion method at 291 K in sodium acetate buffer at pH values near 4.3 using PEG 4000 as precipitant. The crystals presented symmetry compatible with the space group P4(1)2(1)2 or P4(3)2(1)2, with unit-cell parameters a = b = 58.71, c = 93.75 Angstrom, and diffracted to 1.83 Angstrom resolution at the synchrotron source.
