Each … WebInitiation factors are proteins that bind to the small subunit of the ribosome during the initiation of translation, a part of protein biosynthesis. [1] Initiation factors can interact with repressors to slow down or prevent translation. They have the ability to interact with activators to help them start or increase the rate of translation.

WebThe “S” stands for sedimentation coefficient, a measure of where this ribosomal subunit rests in a sedimentation gradient. There are other ribosomal subunits that are also useful for species identification. In eukaryotes, the analogous 16S subunit is larger and is called 18S to reflect its higher sedimentation coefficient. WebRibosomes are made up of a large and a small subunit that come together for translation. The small subunit is responsible for binding the mRNA template, whereas the large …
