Crystallization and preliminary X-ray diffraction results of trichorzianine A 1, A peptide with nineteen residues from Trichoderma harzianum

Add time:07/30/2019    Source:sciencedirect.com

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 Å resolution. The space group is orthorhombic, C2221, Z = 8, a = 64·8 (1) Å, b = 9·33 (3) Å, c = 39·9 (1) Å. The solvent content is only 12%, preventing a heavy ion diffusion. So, we are trying to obtain the structure by direct methods.
