Names and origin

Protein namesRecommended name:
50S ribosomal protein L2
Gene names
Name:rplB
Ordered Locus Names:BUsg_502
OrganismBuchnera aphidicola subsp. Schizaphis graminum (strain Sg) [Complete proteome] [HAMAP]
Taxonomic identifier198804 [NCBI]
Taxonomic lineageBacteriaProteobacteriaGammaproteobacteriaEnterobacterialesEnterobacteriaceaeBuchnera

Protein attributes

Sequence length273 AA.
Sequence statusComplete.
Protein existenceInferred from homology

General annotation (Comments)

Function

One of the primary rRNA binding proteins. Required for association of the 30S and 50S subunits to form the 70S ribosome, for tRNA binding and peptide bond formation. It has been suggested to have peptidyltransferase activity; this is somewhat controversial. Makes several contacts with the 16S rRNA in the 70S ribosome By similarity. HAMAP-Rule MF_01320

Subunit structure

Part of the 50S ribosomal subunit. Forms a bridge to the 30S subunit in the 70S ribosome By similarity.

Sequence similarities

Belongs to the ribosomal protein L2P family.
