UniProtKB - A0QSD4 (RL2_MYCS2)
Protein
50S ribosomal protein L2
Gene
rplB
Organism
Mycolicibacterium smegmatis (strain ATCC 700084 / mc(2)155) (Mycobacterium smegmatis)
Status
Functioni
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.UniRule annotation
