Comments [?]

case <OC:Bacteria>
Function Binds the lower part of the 30S subunit head. Binds mRNA in the 70S ribosome, positioning it for translation.
Subunit Part of the 30S ribosomal subunit. Forms a tight complex with proteins S10 and S14.
end case
case <OC:Archaea>
Function Binds the lower part of the 30S subunit head.
Subunit Part of the 30S ribosomal subunit.
end case
case <OG:Chloroplast>
Subunit Part of the 30S ribosomal subunit.
Subcellular location Plastid, chloroplast.
end case
Similarity Belongs to the universal ribosomal protein uS3 family.

Comments Three plastid proteins have large inserts and are annotated as atypical (CHLRE, ACUOB and STIHE). 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.
