Metallothionein II (M-w =6.8 kDa), induced by cadmium and purified from rab
bit liver, has been crystallized in space group P6(2)22 or P6(4)22; The uni
t-cell parameters were a = b = 113.4, c = 219.1 Angstrom, alpha = beta = 90
.0, gamma = 120.0 degrees when crystallized from sodium citrate buffer and
a = b = 113.4, c = 219.6 Angstrom, alpha = beta = 90.0, gamma = 120.0 degre
es when crystallized from Tris- HCl buffer. There are 12 molecules per asym
metric unit and the solvent: content is about 57%.
