The 1.35 Å structure of cadmium-substituted TM-3, a snake-venom metalloproteinase from Taiwan habu: elucidation of a TNFα-converting enzyme-like active-site structure with a distorted octahedral geometry of cadmium

The high-resolution crystal structure of a snake-venom metalloproteinase (SVMP), TM-3, was solved, which appears to have a stronger resemblance among the known structures of SVMP to the crystal structure of catalytic domain of TNF-converting enzyme (TACE).
