It is the archaeal and eukaryotic ...
It inhibits protein synthesis in the host cell through ADP-ribosylation of the eukaryotic elongation factor 2 (eEF2), which is an essential component for protein synthesis. It is slightly unusual in that it combines the A and B parts in the same protein chain: the pre-toxin is cleaved into two parts, then the two parts are joined by a disulfide ...
While prokaryotes are able to undergo both cellular processes simultaneously, the spatial separation that is provided by the nuclear membrane prevents this coupling in eukaryotes. Eukaryotic elongation factor 2 (eEF2) is a regulateable GTP-dependent translocase that moves nascent polypeptide chains from the A-site to the P-site in the ribosome.
Ternary complex of EF-Tu (blue), tRNA (red) and GTP (yellow). Taken from PDB Molecule of the Month Elongation factors, September 2006.. Elongation factors are a set of proteins that function at the ribosome, during protein synthesis, to facilitate translational elongation from the formation of the first to the last peptide bond of a growing polypeptide.
The C domain blocks protein synthesis by transfer of ADP-ribose from NAD to a diphthamide residue of eukaryotic elongation factor 2 (eEF-2). [7] [3] A central translocation domain, known as the T domain or TM domain, has a multi-helical globin-like fold with two additional helices at the amino terminus but no counterpart to the first globin helix.
The elongation and membrane targeting stages of eukaryotic translation. The ribosome is green and yellow, the tRNAs are dark-blue, and the other proteins involved are light-blue. Elongation depends on eukaryotic elongation factors. At the end of the initiation step, the mRNA is positioned so that the next codon can be translated during the ...
This figure shows that exotoxins are secreted by bacterial cells, Clostridium botulinum for example, and are toxic to somatic cells. Somatic cells have antibodies on the cell wall to target exotoxins and bind to them, preventing the invasion of somatic cells. The binding of the exotoxin and antibody forms an antigen-antibody interaction and the ...
Eukaryotic elongation factor-2 kinase (eEF-2 kinase or eEF-2K), also known as calmodulin-dependent protein kinase III (CAMKIII) and calcium/calmodulin-dependent eukaryotic elongation factor 2 kinase, [5] is an enzyme that in humans is encoded by the EEF2K gene.
