Protein attributes

Sequence length	129 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Located on the platform of the 30S subunit, it bridges several disparate RNA helices of the 16S rRNA. Forms part of the Shine-Dalgarno cleft in the 70S ribosome By similarity.
Subunit structure	Part of the 30S ribosomal subunit. Interacts with proteins S7 and S18 By similarity. Cross-links to IF-3.
Miscellaneous	Has been predicted to contact the N-terminal domain of IF-3 based on footprint studies (Ref.9); exactly how IF-3 interacts with the 30S subunit is controversial. HAMAP MF_01310
Sequence similarities	Belongs to the ribosomal protein S11P family.
Mass spectrometry	Molecular mass is 13727.7 Da from positions 2 - 129. Determined by MALDI. Ref.8
