Figure 4. The modeled structure of crystallin, beta A4 protein (CRYBA4). The modeled structure of CRYBA4 was built using special software (Swiss-PdbViewer 4.0.1 [39-41]). The mutation described in this study leads to the replacement of glycine by tryptophan at codon 64 (Gly64).The Gly64, located in the corner of the modeled structure, may form such secondary structures as β-sheet or β-turn.
