Project Title: Expression and Purification of DNA Polymerase 1 (Klenow Fragment) for Single Molecule Nanotube DNA Sequencing

University of California, Irvine

Dr. Gregory Weiss, PhD, Chemistry Department, University of California, Irvine

Abstract: Errors during DNA synthesis can introduce genomic mutations, and can lead to cancer and other genetic diseases. DNA sequencing can identify these errors at the molecular level, but wide spread application of this technique requires breakthroughs in DNA sequencing. This research examines DNA synthesis using a single molecule of the Klenow Fragment (KF) of DNA Polymerase 1 wired to a single-walled carbon nanotube field effect transistor (SWCNT-FET). If successful, this approach could revolutionize DNA sequencing. KF catalyzes incorporation of deoxynucleotidetriphosphates (dNTPs) into new strands of DNA. During this catalysis, conformational changes in the protein could generate signals specific to each dNTP. However, noise with the signal makes it difficult to distinguish among the dNTPs. We have expressed and purified KF variants designed to enhance the signal to noise ratio. Additional KF variants with different attachment sites could also help in increasing the attachment yields of the protein to the carbon nanotube. Therefore, this research will yield insight into enzyme function at the single-molecule level in order to improve DNA sequencing for medical diagnostics and other purposes.”
