CC   -!- FUNCTION: One of the primary rRNA binding proteins, it binds directly
CC       to 16S rRNA central domain where it helps coordinate assembly of the
CC       platform of the 30S subunit. {ECO:0000255|HAMAP-Rule:MF_01302}.
CC   -!- SUBUNIT: Part of the 30S ribosomal subunit. Contacts proteins S5 and
CC       S12. {ECO:0000255|HAMAP-Rule:MF_01302}.
CC   -!- SIMILARITY: Belongs to the universal ribosomal protein uS8 family.
CC       {ECO:0000255|HAMAP-Rule:MF_01302}.
