Recognition site
5'… GGGCC▼C …3'
3'… C▲CCGGG …5'
Source An E.coli strain that carries the cloned Apa I gene from Acetobacter pasteurianus
Optimal buffer SE-buffer Y + BSA
Optimal temperature 37 °C

BGOWYROSE
50250010050
Unit definition One unit of the enzyme is the amount required to hydrolyze 1 μg of Lambda DNA (dam-dcm-, BamHI-digest) in 1 hour at 37°C in a total reaction volume of 50 μl.
Assayed on Lambda DNA/BamHI
Storage conditions 10 mM Tris-HCl (pH 7.5); 200 mM NaCl; 0.1 mM EDTA; 7 mM 2-mercaptoethanol; 200 μg/ml BSA; 50% glycerol. Store at -20°C.
Ligation After 20-fold overdigestion with enzyme > 95% of the DNA fragments can be ligated and recut.
Nonspecific hydrolysis No nonspecific activity was detected after incubation of 1 μg of Lambda DNA with 40 u.a. of enzyme for 16 hours at 37°C.
Methylation sensitivity Blocked by overlapping Dcm methylation(C m CWGG) GGGC CC WGG
Supplied with enzyme 10 X SE-buffer Y, BSA (except E019T and E020T).
Notes To obtain 100% activity, BSA should be added to the 1x reaction mix to a final concentration of 100 μg/ml. Do not use BSA for long incubation.
