Oxidative damage can have a devastating effect on the structure and activity of proteins, and
may even lead to cell death. The sulfur-containing amino acids cysteine and methionine are …

Accumulation of reactive oxygen and chlorine species (RO/CS) is generally regarded to be a
toxic and highly undesirable event, which serves as contributing factor in aging and many …

Oxidation of methionine (Met) leads to the formation of two S-and R-diastereoisomers of Met
sulfoxide (MetO) that are reduced back to Met by methionine sulfoxide reductases (MSRs), A …

Helicobacter pylori (H. pylori) is a highly successful human pathogen that colonizes stomach
in around 50% of the global population. The colonization of bacterium induces an …

Methionine is a sulfur‐containing residue found in most proteins which are particularly
susceptible to oxidation. Although methionine oxidation causes protein damage, it can in …

Helicobacter and Campylobacter species are Gram-negative microaerophilic host-
associated heterotrophic bacteria that invade the digestive tract of humans and animals …

The well-studied catalytic role of urease, the Ni-dependent conversion of urea into carbon
dioxide and ammonia, has been shown to protect Helicobacter pylori against the low pH …

Bacteria live in different environments and are subject to a wide variety of fluctuating
conditions. During evolution, they acquired sophisticated systems dedicated to maintaining …

Enormous efforts in recent past two decades to eradicate the pathogen that has been
prevalent in half of the world's population have been problematic. The biofilm formed by …

Catalase, a conserved and abundant enzyme found in all domains of life, dissipates the
oxidant hydrogen peroxide (H 2 O 2). The gastric pathogen Helicobacter pylori undergoes …
