Two antifungal proteins, named Eucommia antifungal peptides 1 and 2 (EAFP1 and EAFP2), have been purified from the bark of the tree E. ulmoides Oliver and show a relatively broad spectrum of antifungal activity against several agriculturally important plant pathogens. One of these small proteins (EAFP2) has been crystallized. The crystal belongs to space group P2(1), with unit-cell parameters a = 19.01, b = 23.16, c = 30.69 A, beta = 98.54 degrees. 1.0 A resolution data were collected from an EAFP2 crystal and have been used to obtain phase information directly by an ab initio method.
