Regulation summary diagram for rbbA

RbbA is associated with the 30S subunit of the ribosome and has ribosome-dependent ATPase activity [Kiel99, Kiel01]. Stimulation of protein synthesis by RbbA is dependent on ATP hydrolysis, and the ATPase activity is inhibited by hygromycin [Kiel01, Ganoza01]. The effect of hygromycin may be due to its ability to release RbbA from the ribosome [Ganoza01].

RbbA specifically interacts with EF-Tu and crosslinks to the 30S ribosomal subunit protein S1 [Kiel01]. The E-site base A937 of 16S rRNA in the intact 70S ribosome is protected by a truncated form of RbbA [Xu06b]. The truncated form of RbbA may be identical to the translation factor "Protein W" [Green85, Ganoza85, Ganoza95, Ganoza96, Kiel99]. RbbA also interacts with the membrane protein YhjD and certain lipopolysaccharide transport components [Babu11]. A genetic interaction screen discovered synthetic interactions with genes linked to membrane, protein synthesis and energy metabolism [Babu11].

RbbA contains two ATP-binding domains in its N terminus [Kiel99]. The ATP-binding domains together with five predicted transmembrane helices led to the initial functional prediction as the ATP-binding component of an ABC transporter [Saurin99]. A truncated form of RbbA which does not contain the predicted transmembrane domains still stimulates protein synthesis and has ribosome-dependent ATPase activity [Xu06b].

rbbA yhjD double deletion mutant cells are elongated when grown at 15 or 32°C and show impaired translation fidelity. Both the single and double deletion mutants show increased sensitivity to certain antibiotics that target the ribosome and electron transport by NDH-1 and show impaired growth on glycerol [Babu11].
