Puromycin is an aminonucleoside antibiotic, derived from S. alboniger, that blocks protein synthesis in both prokaryotes and eukaryotes by causing premature termination of nascent polypeptide chains.{21743} A portion of the puromycin molecule resembles the 3′ end of aminoacylated tRNA.{21742} It enters the A site of the ribosome and attaches to the growing polypeptide chain at the peptidyl-transferase center, causing the formation of a puromycylated nascent chain and premature chain release.{21744} The 3′ position contains an amide linkage instead of the normal ester linkage of tRNA, making it much more resistant to hydrolysis and halting the activity of the ribosome.{21744} These properties of puromycin have been exploited in assays for peptide-bond formation and elongation and also the antibiotic is often used as selective agent in cell culture systems.

  • A powerful effector in both the TetR and revTetR transcriptional regulator systems

    Anhydrotetracycline (hydrochloride) – 50 mg

    The tetracycline repressor (TetR) is a transcriptional regulator which normally binds tightly to its palindromic tetO operator DNA, blocking gene expression.{17508} Tet causes the repressor to dissociate from the DNA, allowing transcription to occur. A novel reverse TetR (revTetR) requires tetracycline as a co-repressor to bind tetO and block transcription.{17509,17510} Anhydrotetracycline (hydrochloride) is a powerful effector in both the tetracycline repressor (TetR) and reverse TetR (revTetR) systems, binding the Tet repressor 35-fold more strongly than Tet.{17508,17511} Moreover, anhydrotetracycline poorly binds the 30S ribosomal subunit, compared to Tet,{17512} so it does not act as a general inhibitor of translation and is a poor antibiotic. Perhaps related to this, the concentration of anhydrotetracycline that inhibits eukaryotic cell growth is more than a 1,000-fold above the dose that alters transcription through TetR.{17508}
