Initiation phase of protein synthesis

WebbThe mechanism of translation initiation differs for canonical and leaderless mRNAs, since the latter is dependent on the relative level of the initiation factors. Regulation of translation occurs primarily in the initiation phase. Secondary structures at the mRNA ribosomal binding site (RBS) inhibit translation initiation. Webb14 dec. 2012 · The purpose of this review was to determine whether past research provides conclusive evidence about the effects of type and timing of ingestion of specific sources of protein by those engaged in resistance weight training.

WebbIn bacteria, the initiation phase of protein synthesis involves a limited number of “actors”. Aside from the two ribosomal subunits, key roles are played by the initiator tRNA fmet, the TIR of the mRNA and three protein factors, the initiation factors (IFs) IF1, IF2 and IF3 that ensure speed and accuracy to the overall process [7–9].The initiator tRNA … WebbProtein synthesis occurs in three subcellular compartments, namely, cytoplasm, plastids, and mitochondria ( Figure 2.3 ). Each of them contains different protein synthetic machinery. About 75% of the protein is synthesized in the cytoplasm and 20% in the chloroplast, whereas only a few proteins are synthesized in the mitochondria.
