physiological function | isoforms IsdG and IsdI are both important for Staphylococcus aureus growth on haemin as a sole iron source and are necessary for full Staphylococcus aureus pathogenesis. Strains lacking IsdG, IsdI or both exhibit significantly impaired growth on hemin as a sole iron source when compared with wild-type. Inactivation of IsdG and IsdI in combination does not enhance the hemin utilization defect over that of either individual mutant strain. Overexpression of either IsdG or IsdI complements the loss of both enzymes, and expression of IsdG and IsdI is regulated by iron in a Fur-dependent manner and differentially regulated by iron and hemin | Staphylococcus aureus |

Hemin-dependent upregulation of IsdG is occurring post-transcriptionally by enhancing its protein stability | Staphylococcus aureus |
