Article Synopsis
- Antigen 43 (Ag43) is a key protein in E. coli that aids in biofilm formation and infection, with its expression regulated by phase variation.
- Its expression increases when the cells enter a stationary phase, driven by ppGpp, which boosts the activity of the agn43 promoter rather than altering the proportion of cells expressing agn43.
- The agn43 promoter features a conserved AT-rich region that is essential for the transcriptional regulation by ppGpp, highlighting the importance of promoter activity in Ag43 expression.
