Organism

Corynebacterium urealyticum (strain ATCC 43042 / DSM 7109) [Complete proteome] [HAMAP]

Taxonomic identifier

504474 [NCBI]

Taxonomic lineage

Bacteria › Actinobacteria › Actinobacteridae › Actinomycetales › Corynebacterineae › Corynebacteriaceae › Corynebacterium

Protein attributes

Sequence length	278 AA.
Sequence status	Complete.
Protein existence	Inferred 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 MF_01320_B
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.
