Abstract

The size and shape of aggregates of human recombinant αA-crystallin and αB-crystallin are investigated with small-angle neutron scattering and dynamic light scattering. At a bioactive temperature (310 K), both polypeptides form aggregates with almost the same size and shape. The αB-crystallin maintains an almost identical size and shape at 310 and 288 K, whereas the aggregate of αA-crystallin shows deformation at 288 K. This result suggests that at the lower temperature there is a difference in structural stability between the two aggregates of the polypeptides.
