Bacterial cell division is a fundamental process that requires the coordinated actions of a number of proteins which form a complex macromolecular machine known as the divisome. The membrane‐spanning proteins DivIB and its orthologue FtsQ are crucial divisome components in Gram‐positive and Gram‐negative bacteria respectively. However, the role of almost all of the integral division proteins, including...
The iron‐regulated surface determinant proteins (Isd) of Staphylococcus aureus are expressed during iron limitation and have been proposed to be involved in the scavenging of iron from heme. In this study, the genes encoding the surface proteins IsdA,IsdB, and IsdH were inactivated in order to determine their combined role. The triple mutant was found to have no defect in growth under any conditions...
