Abstract:HUH‐endonucleases (histidine‐hydrophobic‐histidine) create nicks in hairpin loops at the origin of replication during viral rolling circle replication and bacterial plasmid conjugation. Intriguingly, these metal‐dependent enzymes can form rapid, covalent, and specific linkages with single‐stranded DNA (ssDNA) under physiologic conditions. In recent years, we have developed these nucleases as a multiplexable, protein‐DNA bioconjugation (HUH‐tags) technology for live cell imaging, force spectroscopy, genome edit… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
