Crystallization and Preliminary X-Ray Study of H₂-Proteinase from the Venom of Trimeresurus flavoviridis

抄録

H₂-proteinase, a non-hemorrhagic metalloproteinase from the venom of Trimeresurus flavoviridis, has been crystallized by vapor diffusion from solutions containing ammonium sulfate. The crystals belong to the tetragonal space group, P4₁2₁2 or P4₃2₁2, with unit cell dimensions of a=b=77.8 Å and c=82.3 Å. The asymmetric unit contains one protein molecule. Diffraction data for a native crystal were collected up to 2.0 Å resolution.
