PstI

About

PstI is a endonucleasic restriction enzyme isolated from [http://en.wikipedia.org/wiki/Providencia_stuartii Providencia stuartii 164]. It creates stick ends with 3' end overhang.

Working conditions

The recognition motive of EcoRI is: 

5' CTGCAG --> 5'---CTGCA     G---3'
3' GACGTC --> 3'---G     ACGTC---5'

Buffer: NEBuffer 3 + BSA

PstI requires at least 1bp overhang on its cutting site (with reduced cleavage efficiency 37%), more than 3bp (98%) are recommended.[1]
