A groundbreaking approach for single-molecule protein reading has been published in Nature. The technique utilizes ClpX unfoldase to ratchet proteins through a CsgG nanopore, achieving single-amino-acid sensitivity. This advancement, described by researchers including Jeff Nivala and the team from ONT, represents a significant leap in protein sequencing technology. The method allows for multi-pass, single-molecule reading of long protein strands, and can detect post-translational modifications. It requires chemical conjugation of functional amino acids. This development is expected to have profound implications for biological research and understanding protein structures.
