Evidence for a site-specific endonuclease in yeast mitochondria which recognizes the sequence 5'GCCGGC.
We have discovered a mitochondrial, site-specific DNase in Saccharomyces cerevisiae with properties like that of a Type II restriction endonuclease. The enzyme, termed SceIII, cleaves the palindromic sequence 5'GCCGGC, to give 3' ends recessed by 4 bases. SceIII is the first restriction-like endonuclease to be described in yeast mitochondria.
