The P-site (for peptidyl) is the second binding site for tRNA in the ribosome. The other two sites are the A-site (aminoacyl), which is the first binding site in the ribosome, and the E-site (exit), the third. During protein translation, the P-site holds the tRNA which is linked to the growing polypeptide chain. When … See more The ribosomal P-site plays a vital role in all phases of translation. Initiation involves recognition of the start codon (AUG) by initiator tRNA in the P-site, elongation involves passage of many elongator tRNAs through the P … See more Oxazolidines (e.g. linezolid) prevent the binding of the initiator tRNA at the P-site. Oxazolidines have been demonstrated to pleiotropically affect … See more The complete three-dimensional structure of the T. thermophilus 70S ribosome was determined using X-ray crystallography, containing mRNA and tRNAs bound to the P and E sites at 5.5 Å resolution and to the A site at 7 Å resolution. Authors found that all three tRNA … See more WebA quick definition A ribosome is a particle-like cell organelle made of RNA (ribonucleic acid) and ribosomal proteins that serve as the site for protein synthesis in the cell.

WebMay 7, 2024 · The translation is the second part of the central dogma of molecular biology: RNA --> Protein. It is the process in which the genetic code in mRNA is read to make a protein. The translation is illustrated in Figure 6.4. 6. After mRNA leaves the nucleus, it moves to a ribosome, which consists of rRNA and proteins. ticks treatment for yard
