Source:<\/strong> An E.coli strain that carries the cloned Afe I gene from Alcaligenes faecalis T2774
Unit definition:<\/strong>
One unit of the enzyme is the amount required to hydrolyze 1 μg of Lambda DNA (BamHI-digest) in 1 hour at 37°C in a total reaction volume of 50 μl.
Assayed on:<\/strong>
Lambda DNA (BamHI-digest)
Optimal SE-buffer:<\/strong> SE-buffer Y

Storage conditions<\/strong>: 10 mM Tris-HCl (pH 7.6); 50 mM NaCl; 0.1 mM EDTA; 1 mM DTT; 200 μg\/ml BSA; 50% glycerol; Store at -20°C.
Ligations<\/strong>:
After 10-fold overdigestion with enzyme more than 80% of DNA pBR322 fragments can be ligated and recut.
Non-specific hydrolisis<\/strong>:
No nonspecific activity was detected after incubation of 1 μg of DNA with 40 u.a. of enzyme for 16 hours at 37°C.<\/td>\n<\/tr>\n

Reagents Supplied with Enzyme<\/strong>:
Methylation sensitivity<\/strong>: not tested
Notes:<\/strong> The minimum number of units that resulted in complete digestion of 1 μg of substrate DNA in 16 hours is 0,25.AfeI cleaves supercoiled and linear plasmid DNA (pBR322) at a roughly equal rate. AfeI cleaves Lambda DNA\/BamHI digest at a rate 3-4 times higher than plasmid DNA.
