  • PubMed Abstract: 
  • The betagamma-crystallins belong to a superfamily of two-domain proteins found in vertebrate eye lenses, with distant relatives occurring in microorganisms. It has been considered that an eukaryotic stress protein, spherulin 3a, from the slime mold Physarum polycephalum shares a common one-domain ancestor with crystallins, similar to the one-domain 3-D structure determined by NMR ...
