Bacteriophage P1 protein Icd inhibits bacterial division by targeting FtsZ

The study of bacteriophage (phage) gene products and their effects on the host helps to better understand the phage-host relationship and provides clues for the development of new antimicrobial proteins. In this study, we focused on a small protein named Icd with 73 amino acids from phage P1. It inh...

description The study of bacteriophage (phage) gene products and their effects on the host helps to better understand the phage-host relationship and provides clues for the development of new antimicrobial proteins. In this study, we focused on a small protein named Icd with 73 amino acids from phage P1. It inhibits the growth of Escherichia coli and rapidly blocks the formation of Z-ring. The results of bacterial two-hybrid and pull-down experiments showed that Icd directly targets FtsZ, a key protein in bacterial division. Furthermore, we identified the core region of Icd as amino acids 12–51; this 40-amino acid protein had similar antibacterial activity to the full-length Icd, inhibiting bacterial growth and division.
