Nanopore DNA sequencing.png
(A) A single Mycobacterium smegmatis porin A (MspA) channel is inserted into a lipid bilayer membrane. Positive (blue) K+ions and negative (red) Cl- ions are contained on either side of the membrane. An applied electric field drives K+ ions from the trans chamber to the cis chamber and Cl-ions from cis to trans through MspA, producing the unblocked pore current. The region shaded in red at the base of the pore marks the constriction zone of MspA. (B) A motor enzyme controls the translocation of single stranded DNA through MspA. In the schematic depicted here, the motor enzyme translocates and unwinds double stranded DNA (dsDNA), allowing the passage of the ssDNA further into the pore with each step. The flow of both K+ and Cl- ions is modulated by the presence of the DNA within the pore.
