Escherichia coli and Salmonella isolates produce a range of different polysaccharide
structures that play important roles in their biology. E. coli isolates often possess capsular …

Structural analysis of protein tyrosine phosphatases (PTPs) has expanded considerably in
the last several years, producing more than 200 structures in this class of enzymes (from 35 …

Bacterial extracellular polysaccharides (EPSs) play critical roles in virulence. Many bacteria
assemble EPSs via a multi-protein “Wzx-Wzy” system, involving glycan polymerization at the …

Contact‐dependent growth inhibition (CDI) is a phenomenon by which bacterial cell growth
is regulated by direct cell‐to‐cell contact via the CdiA/CdiB two‐partner secretion system …

Protein tyrosine phosphatases (PTPs) play a critical role in physiological signaling pathways
by controlling the level of tyrosine phosphorylation. The past decade has seen a vast …

Many Gram-positive and Gram-negative bacteria utilize polysaccharide surface layers called
capsules to evade the immune system; consequently, the synthesis and export of the …

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

Bacteria evolving resistance against the action of multiple drugs and its ability to
disseminate the multidrug resistance trait (s) across various strains of the same bacteria or …

Bacterial tyrosine kinases (BY-kinases) comprise a family of protein tyrosine kinases that are
structurally distinct from their functional counterparts in eukaryotes and are highly conserved …

Protein phosphorylation represents a key post-translational modification that is critical to the
control of many cellular functions. The reversible phosphorylation of tyrosine residues of …
