Kawasaki K, et al. (1991) DNA sequence recognition by a eukaryotic sequence-specific endonuclease, Endo.SceI, from Saccharomyces cerevisiae. J Biol Chem 266(8):5342-7
Abstract: A eukaryotic sequence-specific endonuclease, Endo.SceI, causes sequence-specific double-stranded scission of double-stranded DNA to produce cohesive ends with four bases protruding at the 3' termini. Unlike in the case of restriction enzymes, an asymmetric 26-base pair consensus sequence was found around the cleavage site for Endo.SceI instead of a common sequence. We analyzed the base pairs that interacted with Endo.SceI on the recognition of its cleavage sites. A region comprising -10 through +16 base pairs from the center of the cleavage site was shown to be essential and sufficient for the sequence-specific cutting with Endo.SceI by experiments involving synthesized DNAs. Methylation interference experiments indicate that bases in the region comprising the +7 through +14 base pairs is involved in close contact with Endo.SceI in its recognition of the cleavage site. This +7 through +14-base pair region overlaps the most stringently conserved sequence in the consensus sequence for the cleavage site, suggesting that this region constitutes the core for the recognition by Endo.SceI.
