The protein synthesis of Ceteuisiae fermentum cell was inhibited by NCS when they were cultured in the medium with ~(35)S-Met.3. The Ceteuisiae fermentum cells treated with NCS were mostly in G1 stage during the cell cycle measurement. The amount of cells in Gl stage increased about 20% compared to the control. These data suggested that the process of protein synthesis may be inhibited or prolonged by NCS.
