  2. Eukaryotic translation - Wikipedia

    en.wikipedia.org/wiki/Eukaryotic_translation

    Translation initiation is the process by which the ribosome and its associated factors bind to an mRNA and are assembled at the start codon. This process is defined as either cap-dependent, in which the ribosome binds initially at the 5' cap and then travels to the stop codon, or as cap-independent, where the ribosome does not initially bind ...

  3. Ribosome-binding site - Wikipedia

    en.wikipedia.org/wiki/Ribosome-binding_site

    Prokaryotic ribosomes begin translation of the mRNA transcript while DNA is still being transcribed. Thus translation and transcription are parallel processes. Bacterial mRNA are usually polycistronic and contain multiple ribosome binding sites. Translation initiation is the most highly regulated step of protein synthesis in prokaryotes. [5]

  4. Kozak consensus sequence - Wikipedia

    en.wikipedia.org/wiki/Kozak_consensus_sequence

    For initiation of translation from such a site, other features are required in the mRNA sequence in order for the ribosome to recognize the initiation codon. It is believed that the PIC is stalled at the Kozak sequence by interactions between eIF2 and the −3 and +4 nucleotides in the Kozak position. [ 24 ]

    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 ...

  6. Bacterial translation - Wikipedia

    en.wikipedia.org/wiki/Bacterial_translation

    Initiation of translation in bacteria involves the assembly of the components of the translation system, which are: the two ribosomal subunits (50S and 30S subunits); the mature mRNA to be translated; the tRNA charged with N-formylmethionine (the first amino acid in the nascent peptide); guanosine triphosphate (GTP) as a source of energy, and the three prokaryotic initiation factors IF1, IF2 ...

  7. Translational regulation - Wikipedia

    en.wikipedia.org/wiki/Translational_regulation

    Initiation of translation is regulated by the accessibility of ribosomes to the Shine-Dalgarno sequence. This stretch of four to nine purine residues are located upstream the initiation codon and hybridize to a pyrimidine-rich sequence near the 3' end of the 16S RNA within the 30S bacterial ribosomal subunit .

  9. Bacterial initiation factor - Wikipedia

    en.wikipedia.org/wiki/Bacterial_initiation_factor

    The IF2 initiation factor is a crucial component in the process of protein synthesis. The largest among the three indispensable translation initiation factors is IF-2, which possesses a molecular mass of 97 kDa. [17] [18] The protein has many domains, including an N-terminal domain, a GTPase domain, a linker region, C1, C2, and C-terminal domains.
