Table 3. Effect of R/K substitution at aa446 of RPE65
Interchange of lysine for arginine at aa446 of dog RPE65 increases isomerase activity, while interchanging arginine for lysine at aa446 of mouse RPE65 reduces isomerase activity. 1Production of 11-cis retinol. 2RPE65 immunoreactive protein. 3Calculated as percentage of wildtype value.
