The site-specific endonuclease R Bli736I and methylase M Bli736I were
isolated from strain Bacillus licheniformis 736 using blue agarose, HA
-Ultragel, and heparin-Sepharose chromatography. The enzymes are free
from interfering impurities. R Bli736I recognizes the [GRAPHICS] seque
nce on DNA and cleaves it as indicated by the arrows, creating single-
stranded 4-nucleotide 5'-protruding ends. This enzyme is an isoschizom
er of Eco31I isolated from E. coli.
