Általános leírás
Apa I ends are not compatible with those generated by any other known restriction enzymes.
Isoschizomers
Apa I is an isoschizomer to Bsp 120 I and Psp OMI.
Methylation sensitivity
Apa I is inhibited by 5′-methylcytosine at the sites indicated (*) in the recognition sequence.
Activity in SuRE/Cut Buffer System
Buffer printed in bold face type is the buffer recommended for optimal activity:

Relative activity in complete PCR mix
Relative activity in PCR mix (Taq DNA Polymerase buffer) is 100%. The PCR mix contained target DNA, primers, 10 mM Tris-HCl (pH 8.3, +20°C), 50 mM KCl, 1.5 mM MgCl2, 200 μM dNTPs, 2.5 U Taq DNA polymerase. The mix was subjected to 25 amplification cycles. Activity in reaction buffer of Pwo SuperYield DNA Polymerase PCR Mix is 10%. When supplemented with GC-RICH Solution activity is increased to >100%.
Incubation temperature
+30°C
Unit definition
One unit is the enzyme activity that completely cleaves 1 μg ? × Hind III fragments in 1 hour at +30°C in a total volume of 25 μl SuRE/Cut Buffer A.
Heat inactivation
The enzyme can be heat inactivated by incubating it for 15 minutes at +65°C.

Ligation and recutting assay
Apa I fragments obtained by complete digestion of 1 μg λ × Hind III fragments are ligated with 1 U T4 DNA Ligase in a volume of 10 μl by incubation for 16 hours at +4°C in 66 mM Tris-HCl, 5 mM MgCl2, 5 mM Dithiothreitol, 1 mM ATP, pH 7.5 (at +20°C) resulting in >95% recovery of 1 μg λ × Hind III fragments.
Subsequent re-cutting with Apa I yields >95% of the typical pattern of λ × Hind III× Apa I fragments.
Absence of nonspecific endonucleases
1 μg λ × Hind III fragments is incubated for 16 hours in 50 μl SuRE/Cut Buffer A with excess Apa I. The number of enzyme units which do not change the enzyme-specific pattern is stated in the certificate of analysis.
Absence of exonuclease activity
Approximately 5 μg [3H] labeled calf thymus DNA are incubated with 3 μl Apa I for 4 hours at +37°C in a total volume of 100 μl 50 mM Tris-HCl, 10 mM MgCl2, 1 mM Dithioerythritol, pH approximately 7.5. Under these conditions, no release of radioactivity is detectable, as stated in the certificate of analysis.

The term “Restriction enzyme” originated from the studies of Enterobacteria phage λ (lambda phage) in the laboratories of Werner Arber and Matthew Meselson.
A "restrikciós enzim" kifejezés az Enterobacteria λ-fág (lambda-fág) vizsgálataiból származik Werner Arber és Matthew Meselson laboratóriumaiban.
