GAMMA S CRYSTALLIN C-TERMINAL DOMAIN
Overview
The 2-domain gammaS-crystallin, a highly conserved early evolutionary, off-shoot of the gamma-crystallin family, is located in the water-rich, region of eye lenses. The expressed C-terminal domain, gammaS-C, has been, crystallized and the 2.56 A X-ray structure determined. There are two, domains in the asymmetric unit which pair about a distorted twofold axis., One of the domains has an altered conformation in a highly conserved, region of the protein, the tyrosine corner. The distorted gammaS-C dimer, of domains is compared with the highly symmetrical, equivalent recombinant, dimer of C-terminal domains from gammaB-crystallin. Sequence changes close, to the interface, that distinguish gammaS from the other, gamma-crystallins, are examined in order to evaluate their role in, symmetrical domain pairing.
