Published: December 2003

Several purine and pyrimidine cyclonucleosides were found to be not recognized by several Escherichia coli and yeast DNA N-glycosylases. Interestingly, a non covalent complex was observed between the Lactoccocus lactis formamidopyrimidine-DNA glycosylases (Fpg-Ll) and the cyclonucleosides. This may provide new information on the mechanism involved in the activity of the latter enzyme.
