Escherichia coli K-12 substr. MG1655 Polypeptide: 50S ribosomal subunit protein L31



Gene: rpmE Accession Numbers: EG10889 (EcoCyc), b3936, ECK3928

Regulation Summary Diagram: ?

Component of:
50S ribosomal subunit
ribosome (summary available)

Summary:
The L31 protein is a component of the 50S subunit of the ribosome.

L31 can be isolated in a complex with 5S rRNA and L5, L18, and L25 [Fanning81] and can be crosslinked to tRNA in the P site [Graifer89]. Modeling shows that L31 may participate in the formation, dynamics and stabilization of the S13-L5 bridge [Shasmal10]. L31 may only be loosely associated with the ribosome [Eistetter99].

L31 was found to be phosphorylated [Soung09], and the purified protein binds Zn2+ [Hensley12].

YkgM is a paralog of RpmE that has lost the predicted metal-binding "zinc ribbon" motif [Makarova01a] and was shown to lack bound Zn2+, in contrast to L31 [Hensley12]. The authors propose a model where YkgM can provide the function of L31 in the ribosome under zinc limiting conditions.

Summary:
The ribosome is a complex machinery that translates the genetic code.

A crystal structure of the E. coli ribosome has been determined at 3.5 Å resolution [Schuwirth05]. Additional crystal structures of the ribosome with tRNA bound in two functionally distinct states reveal how a ratchet-like motion of the small and large subunits contributes to translocation, termination of translation, and ribosome recycling [Zhang09a, Dunkle11].

Approximately eight molecules of Zn2+ are bound to the ribosome; therefore, it appears that a large fraction of intracellular Zn2+ is ribosome-associated [Hensley11].
