CRYSTAL STRUCTURE OF THE RNA-BINDING DOMAIN OF THE TRANSCRIPTIONAL TERMINATOR PROTEIN RHO

Overview

Transcription 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.
