KpnI

(Klebsiella pneumoniae OK 8)

5’-G G T A C C-3’
3’-C C A T G G-5’

Reaction Temperature: 37°C

Prototype: KpnI

Inactivation Temperature (20 min): no

Reaction Buffer:

1x Low Buffer: 10 mM Tris-HCl (pH 7.0 at 37°C), 10 mM MgCl2, 1 mM dithiothreitol.

Unit Definition: One unit is the amount of enzyme required to completely digest 1 µg of Ad-2 DNA in 1 hr in a total reaction volume of 50 µl.

Assay Conditions: 10 mM Tris-HCl (pH 7.0 at 37°C), 10 mM MgCl2, 1 mM dithiothreitol and 1 µg of Ad-2 DNA. Incubation is at 37°C for 1 hr in a reaction volume of 50 µl.

Storage Buffer: 10 mM Tris-HCl (pH 7.5 at 22°C), 50 mM KCl, 0.1 mM EDTA, 1 mM dithiothreitol, 200 µg/ml bovine serum albumin and 50% (v/v) glycerol.

Storage Conditions: Store at –20°C.

Quality Control:

Non-specific Endonuclease: Incubation of 10 units of KpnI with 1 µg of Ad-2 DNA at 37°C for 16 hrs (a 160-fold over-digestion) resulted in the same sharp characteristic banding pattern as the standard assay reaction, as determined by agarose gel electrophoresis.

3'-Exonuclease: 5, 10 and 20 units of KpnI and 0.13 µg of 3'-ends of lambda/TaqI fragments (3'-labeled with T4 DNA Polymerase and [³H]dGTP and [³H]dCTP), incubated for 1 hr at 37°C resulted in -0.03 slope of %-end label released per unit of enzyme. Reaction volume 10 µl.

5'-Exonuclease/5'-Phosphatase: Incubation of 5, 10 and 20 units of KpnI with 0.05 µg 5'-ends of [5'-³³P] lambda/HaeIII fragments for 1 hr at 37°C resulted in 0.001 slope of %-end label released per unit of enzyme. Reaction volume 10 µl.
