Functional domains of a Rho protomer of E. coli Rho. The figure shows an open ‘key washer’ like pentameric form of Rho. Each protomer has four defined functional domains: Primary RNA binding domain that can bind to a single stranded DNA molecule as well as single stranded RNA molecule extending from residues 22 to 116; P-loop, for ATP binding and ATPase activity, includes residues from 179-183; Q-loop, from 278-290 and R-loop from 322-326 comprising the secondary RNA binding site of Rho.
