Engineering ClpXP for Single-Molecule Protein Sequencing

Single-molecule protein sequencing through fingerprinting: computational assessment.

Proteins are vital in all biological systems as they constitute the main structural and functional components of cells. Recent advances in mass spectrometry have brought the promise of complete proteomics by helping draft the human proteome. Yet, this commonly used protein sequencing technique has fundamental limitations in sensitivity. Here we propose a method for single-molecule (SM) protein ...

Advances in Single-molecule Nucleic Acid Sequencing

The ability to quickly and accurately obtain sequence information from single molecules of DNA and RNA has far-reaching implications for our understanding of biology. In the work presented here, we have made several advances in the area of single-molecule DNA and RNA sequencing. Specifically, in attempting to increase the read length of DNA polymerase, we have assayed several custom synthesized...

Read Mapping Algorithms for Single Molecule Sequencing Data

Single Molecule Sequencing technologies such as the Heliscope simplify the preparation of DNA for sequencing, while sampling millions of reads in a day. Simultaneously, the technology suffers from a significantly higher error rate, ameliorated by the ability to sample multiple reads from the same location. In this paper we develop novel rapid alignment algorithms for two-pass Single Molecule Se...

Continuous base identification for single-molecule nanopore DNA sequencing.

A single-molecule method for sequencing DNA that does not require fluorescent labelling could reduce costs and increase sequencing speeds. An exonuclease enzyme might be used to cleave individual nucleotide molecules from the DNA, and when coupled to an appropriate detection system, these nucleotides could be identified in the correct order. Here, we show that a protein nanopore with a covalent...
