Summary of "The uncharacterized bacterial protein YejG has the same architecture as domain III of elongation factor G."

InterPro family IPR020489 comprises ~1,000 uncharacterized bacterial proteins. Previously we showed that over-expressing the Escherichia coli representative of this family, EcYejG, conferred low-level resistance to aminoglycoside antibiotics. In an attempt to shed light on the biochemical function of EcYejG, we have solved its structure using multinuclear solution NMR spectroscopy. The structure most closely resembles that of domain III from elongation factor G (EF-G). EF-G catalyzes ribosomal translocation and mutations in EF-G have also been associated with aminoglycoside resistance. While we were unable to demonstrate a direct interaction between EcYejG and the ribosome, the protein might play a role in translation. This article is protected by copyright. All rights reserved.

The protein-binding N-terminal domain of human translation elongation factor 1Bβ possesses a dynamic α-helical structural organization.

Translation elongation factor 1Bβ (eEF1Bβ) is a metazoan-specific protein involved into the macromolecular eEF1B complex, containing also eEF1Bα and eEF1Bγ subunits. Both eEF1Bα and eEF1Bβ ensur...

Medical and Biotech [MESH] Definitions

A monomeric calcium-calmodulin-dependent protein kinase subtype that specifically phosphorylates PEPTIDE ELONGATION FACTOR 2. The enzyme lacks a phosphorylatable activation domain that can respond to CALCIUM-CALMODULIN-DEPENDENT PROTEIN KINASE KINASE, however it is regulated by phosphorylation by PROTEIN KINASE A and through intramolecular autophosphorylation.

A family of proteins that share a domain with a four transmembrane-helix architecture referred to as the MARVEL domain. The MARVEL domain proteins play important role in vesicular trafficking and in the formation of TIGHT JUNCTIONS.

Peptide Elongation Factor G catalyzes the translocation of peptidyl-tRNA from the A to the P site of bacterial ribosomes by a process linked to hydrolysis of GTP to GDP.

Protein factors uniquely required during the elongation phase of protein synthesis.

An ADP-ribosylating polypeptide produced by CORYNEBACTERIUM DIPHTHERIAE that causes the signs and symptoms of DIPHTHERIA. It can be broken into two unequal domains: the smaller, catalytic A domain is the lethal moiety and contains MONO(ADP-RIBOSE) TRANSFERASES which transfers ADP RIBOSE to PEPTIDE ELONGATION FACTOR 2 thereby inhibiting protein synthesis; and the larger B domain that is needed for entry into cells.
