Ribosome of viruses
Webb24 dec. 2024 · : The ribosome assembles amino acids into a protein. The specific amino acids are controlled by the mRNA sequence. This is required by all living cells and associated viruses. In most bacteria, the most numerous intracellular structure is the ribosome which is the site of protein synthesis in all living organisms. Webb[1] [2] These peptides share a core sequence motif of DxExNPGP, and are found in a wide range of viral families. 2A peptides are used to help generate polyproteins by causing the ribosome to fail at making a peptide bond. [3] [4] The members of 2A peptides are named after the virus in which they have been first described.
