title: Preliminary crystallographic studies of Limulus polyphemus hemocyanin subunits IIIa, IIIb and IV.
abstract: Crystals of Limulus hemocyanin subunits IIIa, IIIb and IV are suitable for X-ray diffraction analysis. The three-dimensional structure of subunit IV is determined by molecular replacement and non-crystallographic symmetry averaging methods. A tentative model of subunit IIIa is obtained from a partial data set. Both structures, similar to subunit II, could provide primary structure segments suitable for oligonucleotide probe synthesis.
