Extracellular and capsular polysaccharides (EPSs and CPSs) are produced by a wide range
of bacteria, including important pathogens of humans, livestock, and plants. These polymers …

The role of protein phosphatases in pathogenic bacteria has been studied extensively over
the last two decades. Ser/Thr and Tyr phosphatases are associated with growth and …

Biofilm formation enhances the survival and persistence of the facultative human pathogen
Vibrio cholerae in natural ecosystems and its transmission during seasonal cholera …

Autophosphorylation of protein-tyrosine kinases (PTKs) involved in exopolysaccharide and
capsular polysaccharide biosynthesis and transport has been observed in a number of …

Bacteria were thought to be devoid of tyrosine-phosphorylating enzymes. However, several
tyrosine kinases without similarity to their eukaryotic counterparts have recently been …

Protein phosphorylation on tyrosine has been demonstrated to occur in a wide array of
bacterial species and appears to be ubiquitous among prokaryotes. This covalent …

Originally identified as a low molecular weight acid phosphatase, LMW-PTP is actually a
protein tyrosine phosphatase that acts on many phosphotyrosine-containing cellular …

Reversible protein phosphorylation is one of the major mechanisms in the regulation of
protein expression and protein activity, controlling physiological functions of the important …

Similar to other intracellular pathogens, Leishmania parasites are known to evade the
antimicrobial effector functions of host immune cells. To date, however, only a few virulence …

Exposure of the Gram-negative pathogen Pseudomonas aeruginosa to subinhibitory
concentrations of antibiotics increases the formation of biofilms. We exploited this phenotype …
