Ribosome-associated inhibitor A

Gene

Organism
Escherichia coli (strain K12)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

During stationary phase, prevents 70S dimer formation, probably in order to regulate translation efficiency during transition between the exponential and the stationary phases. In addition, during environmental stress such as cold shock or excessive cell density at stationary phase, stabilizes the 70S ribosome against dissociation, inhibits translation initiation and increase translation accuracy. When normal growth conditions are restored, is quickly released from the ribosome. Inhibits translation initiation by blocking the A-site (aminoacyl-tRNA site) and P-site (peptidyl-tRNA site) of the ribosome. Counteracts miscoding (translation errors) particularly efficiently at magnesium concentrations close to those observed in vivo but less efficiently at higher concentrations. Counteraction of miscoding was shown to be stronger than inhibition of translation, suggesting that the former activity could be the main function of RaiA in vivo.6 Publications

Interactioni

Subunit structurei

Associates mainly with 70S ribosomes. Localized at the surface of the 30S ribosomal subunit, at the interface with the 50S subunit. Binds across the channel in the 30S subunit where tRNAs and mRNA interact during protein biosynthesis. Can also associate with 100S ribosomes.
