Abstract:Protein splicing is a self‐catalyzed reaction by which an intein, an intervening polypeptide, catalyzes its own removal from exteins, the flanking polypeptides, as well as ligation of the exteins. We are studying the inteins that interrupt a cell division control protein in the halophilic archaea Haloquadratum walsbyi. Halophiles like H. walsbyi are able to survive in water with high concentrations of sodium chloride. H. walsbyi has four inteins that interrupt the cdc21 gene, and we have studied the two intein… 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.
