30S ribosomal protein S9


30S ribosomal protein S9
Not Available
Gene Name
Escherichia coli (strain K12)
Amino acid sequence
>lcl|BSEQ0009951|30S ribosomal protein S9
Number of residues
Molecular Weight
Theoretical pI
GO Classification
structural constituent of ribosome / tRNA binding
cytosol / cytosolic small ribosomal subunit
General Function
Trna binding
Specific Function
The C-terminal tail plays a role in the affinity of the 30S P site for different tRNAs. Mutations that decrease this affinity are suppressed in the 70S ribosome.
