MetaCyc Polypeptide: 50S ribosomal subunit protein L14

Gene: rplN Accession Numbers: EG10875 (MetaCyc), b3310, ECK3297

Species: Escherichia coli K-12 substr. MG1655

Component of:
50S ribosomal subunit
ribosome

Summary:
The L14 protein is a component of the 50S subunit of the ribosome.

L14 crosslinks to 23S rRNA [Osswald90, Urlaub95]. In the cryo-EM reconstruction of the ribosome, L14 was modelled to be located at the 30S-50S subunit interface, at bridges B5 and B8 [Gao03]. In all-atom molecular dynamics simulations of the ribosome, a structural gate between helices 71 and 92 of 23S rRNA restricts tRNA motion and together with L14 acts as a steric filter for the cognate tRNA [Caulfield12].

L14 interacts directly with ribosomal silencing factor. Amino acid residues in L14 that are essential for this interaction have been identified by mutagenesis [Hauser12].

Based on amino-terminal sequencing of the purified protein, L14 may be identical to Rep helicase stimulatory protein (RHSP) [Smith89, Yancey91]. RHSP forms aggregates on DNA and interacts with rRNA [Yancey91].

Retroregulation of L14 expression by mRNA processing and decay has been studied in E. coli B/r [Liang99].
