CC   -!- FUNCTION: One of the primary rRNA binding proteins, it binds directly
CC       to 16S rRNA where it nucleates assembly of the body of the 30S subunit.
CC   -!- FUNCTION: With S5 and S12 plays an important role in translational
CC       accuracy.
CC   -!- SUBUNIT: Part of the 30S ribosomal subunit. Contacts protein S5. The
CC       interaction surface between S4 and S5 is involved in control of
CC       translational fidelity.
case <OG:Chloroplast>
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast.
end case
CC   -!- SIMILARITY: Belongs to the universal ribosomal protein uS4 family.

Comments: Some plastid-encoded rps4 sequences (EIMTE, HELSJ, STIHE,
 TOXGO), as well as CARRP and NEOSM are quite divergent and thus have been
 made atypical. The second and third copies in the Clostridia have also
 been made atypical. In AZOSB the second copy is truncated and probably not
 functional.
