Abstract:RraB, an inhibitor of the essential endoribonuclease RNE in Escherichia coli, is essential in regulating the abundance of RNA by directly interacting with RNE. In this study, RraB from E. coli was cloned, expressed, purified and crystallized. The crystals belonged to space group P2 1 2 1 2 1 , with unit-cell parameters a = 58.59, b = 58.34, c = 156.95 Å . X-ray diffraction data were collected to a resolution of 2.9 Å . Analysis of the native Patterson map revealed a peak of $37% the height of the origin peak i… 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.
