CMB 311 Study Guide - Quiz Guide: Ribosome-Binding Site, Aminoacyl-Trna, Ef-Tu
Document Summary
The ribosome polymerizes amino acids under the direction of an mrna sequence and this is called translation. Accelerate assembly by preventing the formation of misfolded intermediates. Accelerates conformational changes in rrna during protein synthesis. 30s does contain 16s rrna, however, 50s does not. 3 release factors, rf1, rf2, rf3 ribosome recycling factor rrf mrna assorted trnas. 20 standard amino acids. ribosomal protein modifying enzymes rrna modifying enzymes rrna processing enzymes rrna antitermination factors, nusa, nusb, nusg ribosome assembly factors. There is a feedback control of ribosomal protein expression. r-protein mrnas have secondary structural elements that resemble rrna binding sites. Binding proteins to its own mrna prevents translation. N -formylated enzymatically fmet-trna fmet binds directly to the ribosomal p-site. Cca-3" amino acid attachment site a. interacts with the 50s subunit. Anticodon pairs with mrna codon a. interacts with mrna and the 30s subunit. What enzyme is used? trna charging is attaching the amino acid to the trna.
