Abstract:Here we report the draft annotated genome sequence of Escherichia coli XH140A, which is used to produce L-threonine in industry. The genome sequence will allow the characterization of the molecular mechanisms underlying its beneficial properties.L-Threonine has been widely used as a supplement in the food, pharmaceutical, and cosmetics industries. Currently L-threonine is produced mainly by microbial fermentation. To date, E. coli mutant strains remain the dominant industrial producers of L-threonine (6). Alth… 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.
