DNA molecules containing 5-vinyluracil, 5-vinylcytosine, or 7-deaza-7-vinyladenine were prepared by polymerase incorporation of the corresponding vinyl-modified 2-deoxyribonucleoside triphosphates, and the influence of the vinyl group in the major groove of DNA on the cleavage by diverse type II restriction endonucleases (REs) was studied. The presence of 5-vinyluracil was tolerated by most of the REs, whereas only some REs were able to cleave sequences containing 7-deaza-7-vinyladenine. The enzyme ScaI was found to cleave DNA containing 5-vinylcytosine efficiently but not DNA containing the related 5-ethynylcytosine. All other REs failed to cleave sequences containing any cytosine modifications.
