Abstract:Oligopeptide permease A (OppA) plays an important role in the nutrition of cells and various signaling processes. In archaea, OppA is a major protein present in membrane vesicles of Thermococcales. Because there being no crystal structures of archaeal OppAs determined to date, we report the crystal structure of archaeal OppA from Thermococcus kodakaraensis (TkOppA) at 2.3 Å resolution by the single‐wavelength anomalous dispersion method. TkOppA consists of three domains similarly to bacterial OppAs, and the in… 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.
