tetaine inhibits the incorporation of 3H-Ala and 3H-Lys to murein of S. aureus/Oxford/. The inhibition occurs possibly at the level of incorporation of L-Ala to UDP-Mur-NAc, as in the presence of tetaine nucleotide precursors of murein synthesis were radioactive due to 3H-uridine and not 3H-Ala or 3...
