UniProt functional annotation for P14124



	UniProt functional annotation for P14124

UniProt code: P14124.

Organism: Haloarcula marismortui (strain ATCC 43049 / DSM 3752 / JCM 8966 / VKM B-1809) (Halobacterium marismortui).

Taxonomy: Archaea; Euryarchaeota; Stenosarchaea group; Halobacteria; Halobacteriales; Haloarculaceae; Haloarcula.

Function: This is 1 of 5 proteins that mediates the attachment of the 5S rRNA onto the large ribosomal subunit, stabilizing the orientation of adjacent RNA domains. Forms part of the central protuberance. Modeling places the A and P site tRNAs in close proximity to this protein; the 5S rRNA and some of its associated proteins might help stabilize positioning of ribosome-bound tRNAs. In the 70S ribosome it is thought to contact protein S13 of the 30S subunit (bridge B1b), connecting the 2 subunits; this bridge is implicated in subunit movement.

Subunit: Part of the 50S ribosomal subunit. Interacts with protein L18 and the 5S rRNA, and probably with tRNAs. Forms a bridge to the 30S subunit in the 70S ribosome (By similarity). {ECO:0000250}.

Similarity: Belongs to the universal ribosomal protein uL5 family. {ECO:0000305}.
