Mechanisms Of Functioning And Control Of Heme Uptake In Gram-Negative Pathogenic Bacteria

Iron is one of the most important micronutrients used by bacteria, essential for their basic metabolism. Over 70% of bioavailable iron in mammals is in the heme molecule. Gram-negative pathogenic bacteria during colonization and infection of the host organism use heme as the main source of iron. Bacteria have developed two types of outer membrane receptors/transporters involved in the heme uptake. The first one focuses on the receptors...
