Recognition Sequence: 5
Heat inactivation: 20 minutes at 65°C. Ligation and recutting: After 100-fold overdigestion with Nhe I, >98 % of the DNA fragments can be ligated and recut. Note: Activity inhibited by salt concentrations > 100mM. Cleaves to leave a 5' CTAG extension which can be efficiently ligated to DNA fragments generated by Avr II, Spe I, or Xba I. Star activity: Large excess of the enzyme may results in the appearance of star activity. DNA Methylation: No Inhibition: dcm, dam Inhibition (Blocked by some combinations of overlapping): CpG Unit Definition: One unit is the amount of enzyme required to completely digest 1 µg of Lambda DNA (Hind III digest; 1 site) in 1 hour in a total reaction volume of 50 µl. Enzyme activity was determined in the recommended reaction buffer.
