Figure 4. Positions of catalytic domain mutations P858S and L954P
The identified LCA alterations L954P and P858S are situated in the catalytic domain of the protein, and they are both in absolutely conserved amino-acids. Shown is a catalytic domain model of RetGC-1 [38,39], indicating the positions of Leu954 and Pro858. P858S is next to the dimerization domain, while L954P is in the center of an alpha helical loop.
