Gallium nitrate (Ganite) is a potential drug for the treatment of Pseudomonas aeruginosa infection. CRISPR/Cas9-based gene mutagenesis studies reveal that siderophore pyochelin-facilitated uptake and an ABC transporter are two major Ga 3+ internalization pathways in Pseudomonas aeruginosa ( P. aeruginosa ). Crystal structures reveal that Ga 3+ and Fe 3+ occupy exactly the same metal site of HitA, a periplasmic iron-binding protein of the ABC transporter system. The study provides a molecular basis for Ga 3+ internalization by P. aeruginosa and facilitates gallium-based antimicrobial drug development.
