Avidin is a tetrameric protein that belongs to the calycin superfamily. It has been studied mainly because of its extraordinary affinity to biotin, which led to a wide range of applications based on the avidin-biotin system. In the present study, we report the first crystal structures of avidin in a complex with two novel fluorescent pyrene derivatives: 1-biotinylpyrene (B9P) and 1-desthiobiotinylpyrene (D9P) ...
