The regulator PerR is involved in oxidative stress response and iron homeostasis and is necessary for full virulence of Streptococcus pyogenes. (2002)

Ricci, Susanna, Janulczyk, Robert, Björck, Lars

Ferric uptake regulator (Fur) and Fur-like proteins form an important family of transcriptional regulators in many bacterial species. In this work we have characterized a Fur-like protein, the...

Studies on surface proteins of Gram-positive bacteria (2001)

Janulczyk, Robert

Despite the availability of antibiotics and modern health care, infectious diseases continue to cause great suffering and costs. Bacterial surface proteins are important for the interaction between...

Improved Pattern for Genome-Based Screening Identifies Novel Cell Wall-Attached Proteins in Gram-Positive Bacteria

Janulczyk, Robert, Rasmussen, Magnus

With a large number of sequenced microbial genomes available, tools for identifying groups or classes of proteins have become increasingly important. Here we present an improved pattern for the...

MtsABC Is Important for Manganese and Iron Transport, Oxidative Stress Resistance, and Virulence of Streptococcus pyogenes

Janulczyk, Robert, Ricci, Susanna, Björck, Lars

MtsABC is a Streptococcus pyogenes ABC transporter which was previously shown to be involved in iron and zinc accumulation. In this study, we showed that an mtsABC mutant has impaired growth,...
