Functional Description

 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.
