RESUMO
The calculated in vivo polypeptide chain growth rate for Staphylococcus auteus MF-31 grown in nutritionally rich medium assuming all the ribosomes were functional was found to be approximately 16 amino acids/s/ribosome, but decreased to 10.2 amino acids/s/ribosome for cells grown in poor medium. An in vitro analysis revealed that 70S ribosomes isolated from rich medium cells were more active than similar 70S ribosomes derived from cells grown in poor medium. The 30S subunit was found responsible for the increased activity of the rich monosomes, whereas the 50S subunit appeared to be capable of either high or low activity.
