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> | |

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. MALP2 has a very long C-terminal tail and has been made atypical. |
