WebbHfq has been found to be associated with ribosomes (Kajitani et al. 1994). Thus, the formal possibility existed that Hfq associated with ribosomes per se prevents ribosome binding to the ompA RBS. Therefore, 30S ribosomes were added in molar excess over Hfq, which in turn was added in excess over mRNA (see legend to Fig.4A).
