Comments

case <OC:Bacteria>
FUNCTION: Binds the lower part of the 30S subunit head. Binds mRNA in the 70S ribosome, positioning it for translation (By similarity).
SUBUNIT: Part of the 30S ribosomal subunit. Forms a tight complex with proteins S10 and S14 (By similarity).
end case


case <OC:Archaea>
FUNCTION: Binds the lower part of the 30S subunit head (By similarity).
SUBUNIT: Part of the 30S ribosomal subunit (By similarity).
end case


case <OG:Chloroplast>
SUBUNIT: Part of the 30S ribosomal subunit (By similarity).
SUBCELLULAR LOCATION: Plastid, chloroplast.
end case

SIMILARITY: Belongs to the ribosomal protein S3P family.

case <Feature:PS50823>
SIMILARITY: Contains 1 KH type-2 domain.
end case

Comments: Three plastid proteins have large inserts and are annotated as atypical (CHLRE, SCEOB and STIHE). Several other proteins are quite divergent and also atypical; CARRP, CENSY, HELSJ and NANEQ. Some of the proteins have C-terminal tails; after about 225 residues sequences aren't conserved. MYCPE has a very long C-terminal tail and has been made atypical.
