A bacterial initiation factor (IF) is a protein that stabilizes the initiation complex for polypeptide translation. Translation initiation is essential...

Bacterial initiation factor 1 is a bacterial initiation factor. IF1 associates with the 30S ribosomal subunit in the A site and prevents an aminoacyl-tRNA...

Bacterial initiation factor-2 is a bacterial initiation factor. IF2 binds to an initiator tRNA and controls the entry of tRNA onto the ribosome. IF2, bound...

In molecular biology, initiation factors are proteins that bind to the small subunit of the ribosome during the initiation of translation, a part of protein...

factor (σ factor or specificity factor) is a protein needed for initiation of transcription in bacteria. It is a bacterial transcription initiation factor...

Eukaryotic initiation factors (eIFs) are proteins or protein complexes involved in the initiation phase of eukaryotic translation. These proteins help...

called promoters. The binding of the σ-factor to the promoter is the first step in initiation. Once the σ-factor releases from the polymerase, elongation...

Bacterial translation is the process by which messenger RNA is translated into proteins in bacteria. Initiation of translation in bacteria involves the...

molecular biology, translation initiation factor IF-3 (gene infC) is one of the three factors required for the initiation of protein biosynthesis in bacteria...

such as insulin, growth factors, or antibodies. Because of their importance for research in general, samples of bacterial strains are isolated and preserved...

Archaeal initiation factors are proteins that are used during the translation step of protein synthesis in archaea. The principal functions these proteins...

release factors are GTPases that enhance the activity of class 1 release factors. It helps the class 1 RF dissociate from the ribosome. Bacterial release...

transcription factors. It is encoded by the TFIIB gene, and is homologous to archaeal transcription factor B and analogous to bacterial sigma factors. TFIIB...

IF2 may refer to: Bacterial initiation factor 2 (IF-2) IF2 on the International Fujita scale, a tornado rating Interceptor Force 2, a 2002 science fiction...

phases: initiation, elongation, termination, and recapping. Translation initiation is the process by which the ribosome and its associated factors bind to...

for the recruitment of a ribosome during the initiation of translation. Mostly, RBS refers to bacterial sequences, although internal ribosome entry sites...

throughout the bacterial kingdom, their specific positioning and spacing in a given species are critical for oriC function and for productive initiation complex...

added to the amino group. It is specifically used for initiation of protein synthesis from bacterial and organellar genes, and may be removed post-translationally...

transcription factors are necessary for transcription to occur. In bacteria, transcription initiation requires an RNA polymerase and a single GTF: sigma factor. In...

promoters combined with general transcription factors are sufficient to direct transcription initiation, but generally have low basal activity. Other...

multiple influences on transcription and translation in bacterial cells. Integration host factor, IHF, is not a nucleoid-associated protein only found in...

Bacterial meningitis is a bacterial inflammation of the meninges, which are the protective membranes covering the brain and spinal cord. Bacterial pneumonia...

plays a crucial role in the initiation of chromosomal DNA replication. Bound to ATP, and with the assistance of bacterial histone-like proteins [HU] DnaA...
