CRYSTAL STRUCTURE OF THE RNA-BINDING DOMAIN OF THE TRANSCRIPTIONAL TERMINATOR PROTEIN RHOCRYSTAL STRUCTURE OF THE RNA-BINDING DOMAIN OF THE TRANSCRIPTIONAL TERMINATOR PROTEIN RHO
Structural highlights
FunctionRHO_ECOLI Facilitates transcription termination by a mechanism that involves rho binding to the nascent RNA, activation of rho's RNA-dependent ATPase activity, and release of the mRNA from the DNA template. RNA-dependent NTPAse which utilizes all four ribonucleoside triphosphates as substrates.[HAMAP-Rule:MF_01884] Evolutionary Conservation![]() Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedTranscription termination factor rho is an ATP-dependent hexameric helicase found in most eubacterial species. The Escherichia coli rho monomer consists of two domains, an RNA-binding domain (residues 1-130) and an ATPase domain (residues 131-419). The ATPase domain is homologous to the beta subunit of F1-ATPase. Here, we report that the crystal structure of the RNA-binding domain of rho (rho130) at 1.55 A confirms that rho130 contains the oligosaccharide/oligonucleotide-binding (OB) fold, a five stranded beta-barrel. The beta-barrel of rho130 is also surprisingly similar to the N-terminal beta-barrel of F1 ATPase, extending the applicability of F1 ATPase as a structural model for hexameric rho.
