• protein synthesis
  • Ribosomes, the organelles that catalyze protein synthesis, consist of a small 40S subunit and a large 60S subunit. (nih.gov)
  • Pokeweed antiviral protein (PAP) from Phytolacca americana is a ribosome inactivating protein (RIP) and is an RNA N -glycosidase that removes specific purine residues from the sarcin/ricin (S/R) loop of large rRNA, arresting protein synthesis at the translocation step. (mdpi.com)
  • In bacteria, protein synthesis stalls when the ribosome reaches the 3'-end of truncated mRNA transcripts lacking a stop codon. (byu.edu)
  • A portion of the C-terminal tail forms a helix within the mRNA channel, monitoring the length of mRNA bound in the ribosome to avoid aborting productive protein synthesis. (byu.edu)
  • Together with RPL4, RPL22 forms the narrowest constriction of the ribosomal exit tunnel (the grove through which a growing protein chain exits the ribosome), and consequently mutations in RPL22 are believed to alter the efficiency with which protein synthesis proceeds. (wikipedia.org)
  • chain
  • Transfer-messenger RNA (tmRNA) and its protein partner SmpB mimic a tRNA by entering the A site of the ribosome and accepting the growing peptide chain. (byu.edu)
