Control of A Multisubunit DNA Motor by a Thermoresponsive Polymer Switch
摘要:
The conjugation of thermoresponsive polymers to multisubunit, multifunctional hybrid type 1 DNA restriction-modification (R-M) enzymes enables temperature-controlled "switching" of DNA methylation by the conjugate. Polymers attached to the enzyme at a subunit distal to the methylation subunit allow retention of DNA recognition and ATPase activity while controlling methylation of plasmid DNA. This regulation of enzyme activity arises from the coil-globule phase transitions of the polymer as shown in light scattering and gel retardation assays.

The present invention refers to new classes of polymerisable monomers, to molecularly imprinted polymers obtainable by polymerisation of at least one of the monomers and a crosslinking monomer in the presence of a template molecule. The obtained polymers may be used for separation of enantiomers, diastereomers of the template molecule, and also for separation of the template molecule or template molecule analogues from structurally related compounds.
