General annotation (Comments)

Function

One of the primary rRNA binding proteins, it binds directly to 16S rRNA central domain where it helps coordinate assembly of the platform of the 30S subunit By similarity. HAMAP-Rule MF_01302_B

Protein S8 is a translational repressor protein, it controls the translation of the spc operon by binding to its mRNA. HAMAP-Rule MF_01302_B

Subunit structure

Part of the 30S ribosomal subunit. Contacts proteins S5 and S12 By similarity.

Sequence similarities

Belongs to the ribosomal protein S8P family.

Mass spectrometry

Molecular mass is 13993.2 Da from positions 2 - 130. Determined by MALDI. Ref.8
