Recognition site:



Source: An E.coli strain that carries the cloned Pcs I gene from Paracoccus carotinifaciens 3K.

Substrate specificity:

Unit definition: 

One unit is defined as the amount of enzyme required to digest 1 µg of pMHpySE49/DriI DNA in 1 hour at 37°C in a total reaction volume of 50 µl. As a result, a linearized plasmid pMHpySE49/DriI disappears, and two DNA fragments are produced.


PcsI activity assay on pMHpySE49/DriI DNA
Lanes:1 and 7 – 1 Kb SE DNA-ladders
2 – Control pMHpySE49/DriI
3 – 0.25 μl Pcs I
4 – 0.5 μl Pcs I
5 – 1 μl Pcs I
6 – 2 μl Pcs I

Products were separated in 1,4% TAE agarose gel.

Assayed on:

pMHpySE49 plasmid DNA, linearized with DriI (pMHpySE49/DriI).
pMHpySE49 (3536 bp) was obtained by a ligation of the vector pMTL22/FauNDI/SmaI and a PCR-fragment containing M.HpySE526I (forms 5′-A(5mC)GT-3′) gene and
DNA sequence:


Thus, the plasmid has the optimal site of PcsI:

Optimal SE-buffer: SE-buffer PcsI
Enzyme activity (%):

50-75 50-75 0 10-25 50-75 50


Storage conditions: 10 mM Tris-HCl (pH 7.5); 200 mM NaCl; 0.1 mM EDTA; 7 mM 2-mercaptoethanol; 0.1 mg/ml BSA, 50% glycerol; Store at -20°C.

Ligation: –

Non-specific hydrolisis: No detectable degradation of 1μg of Lambda DNA was observed after incubation with 1 units of enzyme for 16 hours at 37°C in a total reaction volume of 50 μl.Reagents Supplied with Enzyme

10 X SE-buffer PcsI

Methylation sensitivity: The enzyme cleaves only C5-methylated DNA and does not cut unmodified DNA [1].

Notes: When using a buffer other than the optimal (suppied) SEBuffer, it may be necessary to add more enzyme to achieve complete digestion.
