CC   -!- FUNCTION: One of several proteins that assist in the late maturation
CC       steps of the functional core of the 30S ribosomal subunit. Associates
CC       with free 30S ribosomal subunits (but not with 30S subunits that are
CC       part of 70S ribosomes or polysomes). Required for efficient processing
CC       of 16S rRNA. May interact with the 5'-terminal helix region of 16S
CC       rRNA. {ECO:0000255|HAMAP-Rule:MF_00003}.
CC   -!- SUBUNIT: Monomer. Binds 30S ribosomal subunits, but not 50S ribosomal
CC       subunits or 70S ribosomes. {ECO:0000255|HAMAP-Rule:MF_00003}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00003}.
CC   -!- SIMILARITY: Belongs to the RbfA family. {ECO:0000255|HAMAP-
CC       Rule:MF_00003}.
