Crystallization and preliminary X-ray diffraction results of trichorzianine A 1, a peptide with nineteen residues from Trichoderma harzianum.
Trichorzianine A 1 is one of the main components of a mixture of related antibiotic peptides (trichorzianines) produced by the fungus Trichoderma harzianum. Good crystals were obtained and allowed X-ray diffraction up to 0.8 A resolution. The space group is orthorhombic, C222(1), Z = 8, a = 64.8 (1) A, b = 9.33 (3) A, c = 39.9 (1) A. The solvent content is only 12%, preventing a heavy ion diffusion. So, we are trying to obtain the structure by direct methods.
