While phosphotyrosine modification is an established regulatory mechanism in eukaryotes,
it is less well characterized in bacteria due to low prevalence. To gain insight into the extent …

Double-stranded (ds) DNA contains all of the necessary genetic information, although
practical use of this information requires unwinding of the duplex DNA. DNA unwinding …

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

The effect of the chemical structure of interpolyelectrolyte complexes (IPEC) based on
polymers of natural origin (pectin––chitosan+, pectin––cationic starch (starch+) …

The genomic integrity of Mycobacterium tuberculosis is continuously threatened by the
harsh survival conditions inside host macrophages, due to immune and antibiotic stresses …

Green synthesis of silver-containing nanocomposites based on polylactide (PLA) was
carried out in two ways. With the use of green tea extract, Ag+ ions were reduced to silver …

Background In recent years, an idiosyncratic new class of bacterial enzymes, named BY-
kinases, has been shown to catalyze protein-tyrosine phosphorylation. These enzymes …

Phosphorylation events modify bacterial and archaeal proteomes, imparting cells with rapid
and reversible responses to specific environmental stimuli or niches. Phosphorylated …

Background A challenging goal in biology is to understand how the principal cellular
functions are integrated so that cells achieve viability and optimal fitness in a wide range of …

Natural transformation is a programmed mechanism characterized by binding of free double-
stranded (ds) DNA from the environment to the cell pole in rod-shaped bacteria. In Bacillus …
