CC   -!- FUNCTION: Binds mRNA; thus facilitating recognition of the initiation
CC       point. It is needed to translate mRNA with a short Shine-Dalgarno (SD)
CC       purine-rich sequence (By similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the bacterial ribosomal protein bS1 family.
CC       {ECO:0000305}.
