  • Most bacteria require iron for growth. However, as it may not be directly available under aerobic conditions, bacteria may use iron-sequestering molecules, such as bacterially encoded siderophores, or heme, which is the major iron source in the animal host. Bacteria may also assimilate heme for purposes other than as an iron source. Once internalised, heme can activate, for example, a heme-dependent catalase and a cytochrome oxidase. In bacterial pathogen Streptococcus agalactiae, heme, in… CONTINUE READING
