Introduction 3. Common features of the outer membrane ferric-siderophore transport
proteins 3.1. The FecA protein transports ferric citrate and regulates gene transcription 3.1 …

Induction of the ferric citrate transport genes of Escherichia coli K-12 involves a signalling
cascade that starts at the cell surface and proceeds to the cytoplasm. Three specific proteins …

Staphylococcus aureus pathogenesis is significantly influenced by the iron status of the host.
However, the regulatory impact of host iron sources on S. aureus gene expression remains …

Microbial evolution and subsequent species diversification enable bacterial organisms to
perform common biological processes by a variety of means. The epsilonproteobacteria are …

The bacterial pathogen Staphylococcus aureus is responsible for a significant amount of
human morbidity and mortality, and the ability of S. aureus to cause disease is absolutely …

The important human pathogen Staphylococcus aureus is able to satisfy its nutrient iron
requirement by acquiring heme from host hemoglobin in the context of infection. However …

The initiation, progression and transmission of most bacterial infections is dependent upon
the ability of the invading pathogen to acquire iron from each of the varied environments …

Heme is a versatile molecule that is vital for nearly all cellular life by serving as prosthetic
group for various enzymes or as nutritional iron source for diverse microbial species …

Transcription of the Corynebacterium diphtheriae hmuO gene, which encodes a heme
oxygenase involved in heme iron utilization, is activated in a heme-or hemoglobin …

Bordetella pertussis and Bordetella bronchiseptica, gram-negative respiratory pathogens of
mammals, possess a heme iron utilization system encoded by the bhuRSTUV genes …
