Abstract
The present invention relates to: recombinant DNA encoding the SbfI restriction endonuclease as well as the SbfI methylase, and expression of the SbfI restriction endonuclease and SbfI methylase in E. coli cells containing the recombinant DNA; and methods for cloning the SbfI restriction gene (sbfIR) from Streptomyces species Bf-61 into E. coli by PCR. The method relied on primers based on DNA sequences predicted from amino acid sequences of the purified SbfI restriction endonuclease.
Claims6
Isolated DNA encoding the SbfI restriction endonuclease, wherein the isolated DNA is obtainable from Streptomyces species Bf-61.
A recombinant DNA vector comprising a vector into which a DNA segment encoding the SbfI restriction endonuclease has been inserted.
Isolated DNA encoding the SbfI restriction endonuclease and SbfI methylase, wherein the isolated DNA is obtainable from ATCC No. PTA-5371.
