Outline of Final Research Achievements |
Aquifex aeolicus lumazine synthase (AaLS) forms hollow-icosahedral capsule by self-assembling of 60 subunits. A negatively charged lumazine synthase mutant( AaLS_Neg ) is expected as a bio-nanocapsule which can be used for a DDS. In this study, we prepared several AaLS_Neg mutants, each carrying an azido-tyrosine at predetermined positions 22, 40, 44, 57, 91, respectively. The synthesized AaLS_Neg mutant containing azido-tyrosine at position 22 was covalently crosslinked via azide group by UV irradiation. And then, this photo-crosslinked product was separated on a gel filtration column. As a result, we observed that the encapsulation efficiency of photo-crosslinked product was increased.
