action of type III restriction enzymes takes place on replicated or replicating DNA in VIVO and leaves daughter DNAs with breaks at nonallelic sites, that bacteriophage-mediated homologous recombinantion reconstitutes an intact DNA from them, and that REcBCD exonuclease blocks this repair by degradation from the restriction breaks |
| 3.1.21.5 | DNA + H2O |
the intact Res2Mod2 tetramer is a fast endonuclease and slow methyltransferase, thereby favouring DNA cleavage, subassemblies of PstII in which the Res subunits have dissociated are more efficient methyltransferases. DNA cleavage by these lower molecular weight species may only occur if sufficient hsdR associates to form a Res2Mod2 tetramer before methylation occurs. This dynamic association of Res and Mod might play a key role in the control of PstII activity in vivo |

the enzyme uses both diffuse DNA loop formation and ATPase driven translocation of the intervening DNA contour to communicate between two recognition sites |
