These proteins facilitate ...This entry represents a PRC-barrel domain found in the RimM protein family. The RimM family comprises ribosome maturation factors essential for the final assembly of the 30S ribosomal subunit, particularly the head region. These proteins facilitate the efficient processing of 16S rRNA and may function both before and after RbfA during 16S rRNA maturation. RimM proteins have a specific affinity for free 30S ribosomal subunits but not for 70S ribosomes. The PRC barrel domain within these proteins binds to ribosomal protein uS19, playing a crucial role in the assembly process. In some organisms, RimM is one of several proteins, including Era, RbfA, and RsgA/YjeQ, that assist in the late stages of 30S subunit assembly, ensuring the correct assembly of head-associated ribosomal proteins and preventing the accumulation of precursor rRNA forms.
