What proteins do bacteria use to obtain iron from their host? |
Siderophores. Iron is required for growth of most bacteria, however theres very little free iron in the human body, which is why bacteria use siderophores. |
|
|
What are the sequence of events for obtaining iron via siderophores? |
1. Bacterial release 2. Sideorophores take away iron from host iron-transport proteins by binding iron more tightly 3. Once siderophores binds iron (forming an iron-siderophore complex), it returns to the bacterium. 4. Iron-siderophore complex is taken up by receptors on the bacterial surface. Bacterium has iron. |
