Eukaryotic translation is the biological process by which messenger RNA is translated into proteins in eukaryotes. It consists of four phases: initiation, elongation ...
Overview of eukaryotic messenger RNA (mRNA) translation Translation of mRNA and ribosomal protein synthesis Initiation and elongation stages of translation involving RNA nucleobases, the ribosome, transfer RNA, and amino acids The three phases of translation: (1) in initiation, the small ribosomal subunit binds to the RNA strand and the initiator tRNA–amino acid complex binds to the start ...
English: At the initiation phase, the initiator tRNA carrying methionine with its anticodon encounters the AUG start codon at the P-site of the ribosome. During elongation, the ribosome translocates in the 5' to 3' direction, at which point the amino acids attached by peptide bonds to the tRNA in the P-site can bond to the tRNA in the A-site, creating a long amino acid chain based on the ...
Elongation is the most rapid step in translation. [3] In bacteria , it proceeds at a rate of 15 to 20 amino acids added per second (about 45-60 nucleotides per second). [ citation needed ] In eukaryotes the rate is about two amino acids per second (about 6 nucleotides read per second).
Once translation initiation is complete, the first aminoacyl tRNA is located in the P/P site, ready for the elongation cycle described below. During translation elongation, tRNA first binds to the ribosome as part of a complex with elongation factor Tu or its eukaryotic or archaeal counterpart. This initial tRNA binding site is called the A/T site.
The elongation phase starts once assembly of the elongation complex has been completed, and progresses until a termination sequence is encountered. [1] The post-initiation movement of RNA polymerase is the target of another class of important regulatory mechanisms.
EF-G (elongation factor G, historically known as translocase) is a prokaryotic elongation factor involved in mRNA translation. As a GTPase , EF-G catalyzes the movement (translocation) of transfer RNA (tRNA) and messenger RNA (mRNA) through the ribosome .
Elongation factor 1-beta is a protein that in humans is encoded by the EEF1B2 gene. [5] [6] Function. This gene encodes a translation elongation factor.
