Abstract: Trichosanthin (TCS) is a type I ribosome-inactivating protein (RIP) which possesses rRNA N-glycosidase activity. TCS has various pharmacological properties. It is possible to reduce the antigenicity of TCS by deleting up to seven C-terminal residues of TCS (TCS-C7) with minimal effect on its activity [1]. TCS-C7 has been crystallized and the crystal diffracted to 1.8 Å. It belongs to space group P21, with unit-cell parameters a=71.6Å, b=74.4Å, c=87.6Å, β=97.0°. It is given that there are four molecules per asymmetric unit.
