Action Spectra of DNA Photolyases for Photorepair of Cyclobutane Pyrimidine Dimers in Sorghum and Cucumber

Abstract

DNA photolyases that catalyze light-dependent repair of cyclobutane pyrimidine dimers (CPDs) were extracted and partially purified from sorghum and cucumber. The action spectra of CPD photolyases in these plant species had a maximum at 400 nm, which differ from those in Drosophila, Escherichia coli and Anacystis.
