✦ Synopsis

The addition of nalidixic acid to growing cells of the yeast Saccharomyces cerevisiae resulted in a transient depression in the rate of ribosomal precursor RNA production and a transient arrest of cells in G1. Protein synthesis rates were less affected. Lower concentrations of nalidixic acid also affected RNA synthesis and progression through G1 but had no effect on protein synthesis rates. We suggest that nalidixic acid has a primary effect on RNA synthesis leading to a G1 arrest.

The GGP1 (GAS1) gene encodes an exocellular 115-kDa glycoprotein (gpll5) of the yeast Saccharomyces cerevisiae. We have monitored the changes in GGP1 mRNA levels under different conditions of G1 arrest. Transcript levels rapidly decrease during transition from exponential growth to stationary phase.
