== Publication Abstract from PubMed == | |||
Previous attempts to crystallize mammalian gammaS-crystallin were unsuccessful. Native L16 chicken gammaS crystallized avidly while the Q16 mutant did not. The X-ray structure for chicken gammaS at 2.3 A resolution shows the canonical structure of the superfamily plus a well-ordered N arm aligned with a beta sheet of a neighboring N domain. L16 is also in a lattice contact, partially shielded from solvent. Unexpectedly, the major lattice contact matches a conserved interface (QR) in the multimeric beta-crystallins. QR shows little conservation of residue contacts, except for one between symmetry-related tyrosines, but molecular dipoles for the proteins with QR show striking similarities while other gamma-crystallins differ. In gammaS, QR has few hydrophobic contacts and features a thin layer of tightly bound water. The free energy of QR is slightly repulsive and analytical ultracentrifugation confirms no dimerization in solution. The lattice contacts suggest how gamma-crystallins allow close packing without aggregation in the crowded environment of the lens. | |||
