Ribosome maturation factor RimM

Gene

rimM

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

An accessory protein needed during the final step in assembly of the 30S ribosomal subunit, probably for assembly of the head region (also called the 3' domain). It may act while Era is associated and after RimM in 30S subunit assembly. Interacts with S19. Essential for efficient processing of 16S rRNA; a deletion mutant accumulates 17S rRNA. May be needed both before and after RbfA during the maturation of 16S rRNA. It has affinity for free ribosomal 30S subunits but not for 70S ribosomes.3 Publications

Pathology & Biotechi

Disruption phenotypei

Disruption causes incomplete processing of 17S rRNA, accumulation of 30S and 50S subunits and decreased translational efficiency. Deletion is partially suppressed by mutations in rpsM, the gene for ribosomal protein S13, by a mutation in rpsS, the gene for S19 and also by overexpression of RbfA. Suppressors due to in-frame fusions with rpsP, the upstream gene for ribosomal protein S16 have been isolated. Suppression is probably due to increased expression of RimM; the fusion proteins are found in translationally active 70S ribosomes.1 Publication
