Cyclobutane pyrimidine dimers (CPD), as a common DNA damage caused by UV radiation, often lead to skin cancer. Here, we identified a photolyase from the alga Arthrospira platensis (designated as Ap-phr), which has been regarded as a safe organism for humans for centuries, that can efficiently repair CPD lesions in ssDNA and dsDNA in vitro. The 1.6 Å resolution crystal structure of Ap-phr revealed that it possesses a unique methenyltetrahydrofolate chromophore-binding pattern with high energy transfer efficiency. Our study of Ap-phr highlights its potential use in cosmetic, industrial and aesthetic medicine applications.
