It is the archaeal and eukaryotic ...
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.
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.
Elongation factors are targets for the toxins of some pathogens. For instance, Corynebacterium diphtheriae produces diphtheria toxin, which alters protein function in the host by inactivating elongation factor (EF-2). This results in the pathology and symptoms associated with diphtheria. Likewise, Pseudomonas aeruginosa exotoxin A inactivates ...
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 ...
Eukaryotic Initiation Factor 2 (eIF2) is an eukaryotic initiation factor.It is required for most forms of eukaryotic translation initiation. eIF2 mediates the binding of tRNA i Met to the ribosome in a GTP-dependent manner. eIF2 is a heterotrimer consisting of an alpha (also called subunit 1, EIF2S1), a beta (subunit 2, EIF2S2), and a gamma (subunit 3, EIF2S3) subunit.
The positive transcription elongation factor, P-TEFb, is a multiprotein complex that plays an essential role in the regulation of transcription by RNA polymerase II (Pol II) in eukaryotes. [1] Immediately following initiation Pol II becomes trapped in promoter proximal paused positions on the majority of human genes (Figure 1).
In enzymology, an elongation factor 2 kinase (EC 2.7.11.20) is an enzyme that catalyzes the chemical reaction: ATP + [elongation factor 2] ⇌ {\displaystyle \rightleftharpoons } ADP + [elongation factor 2] phosphate.
