Abstract
The invention relates to a new method of characterizing a target polynucleotide. The method uses a pore and a Hel308 helicase or a molecular motor which is capable of binding to the target polynucleotide at an internal nucleotide. The helicase or molecular motor controls the movement of the target polynucleotide through the pore.

-43. (canceled)
A method of characterising a target polynucleotide, comprising:
- (a) contacting the target polynucleotide with a transmembrane pore such that a portion of the target polynucleotide is captured by a transmembrane pore, wherein the pore is present in a membrane;
- (b) contacting the target polynucleotide with a Hel308 helicase such that the helicase binds to the target polynucleotide, thereby controlling the movement of the target polynucleotide through the transmembrane pore;
- and
- (c) measuring one or more characteristics of the target polynucleotide as the target polynucleotide moves through the transmembrane pore, thereby characterising the target polynucleotide.
