Abstract

Fis is a small basic DNA-binding protein from Escherichia coli that was identified because of its role in site-specific DNA recombination reactions. Recent evidence indicates that Fis also participates in essential cell processes such as rRNA and tRNA transcription and chromosomal DNA replication. In this report, we show that Fis levels vary dramatically during the course of cell growth and in response to changing environmental conditions. When stationary-phase cells are subcultured into a rich medium, Fis levels increase from less than 100 to over 50,000 copies per cell prior to the first cell division. As cells enter exponential growth, nascent synthesis is largely shut off, and intracellular Fis levels decrease as a function of cell division. Fis synthesis also transiently increases when exponentially growing cells are shifted to a richer medium. The magnitude of the peak of Fis synthesis appears to reflect the extent of the nutritional upshift. fis mRNA levels closely resemble the protein expression pattern, suggesting that regulation occurs largely at the transcriptional level. Two RNA polymerase-binding sites and at least six high-affinity Fis-binding sites are present in the fis promoter region. We show that expression of the fis operon is negatively regulated by Fis in vivo and that purified Fis can prevent stable complex formation by RNA polymerase at the fis promoter in vitro. However, autoregulation only partially accounts for the expression pattern of Fis. We suggest that the fluctuations in Fis levels may serve as an early signal of a nutritional upshift and may be important in the physiological roles Fis plays in the cell.
