Genomic studies have revealed the presence of Ser/Thr kinases and phosphatases in many
bacterial species, although their physiological roles have largely been unclear. Here we …

In bacteria, extracellular signals are generally transduced into cellular responses via a two-
component system. However, genome sequence data have now revealed the presence of …

PrkC was shown to be a eukaryotic‐like (Hanks‐type) protein kinase from Bacillus subtilis
with a struc‐tural organization similar to that of the eukaryotic sensor Ser/Thr or Tyr kinases …

In bacteria, regulatory phosphorylation of proteins at serine and/or threonine residues by
Ser/Thr protein kinase (STPK) is an emerging theme in prokaryotic signaling, particularly …

Reversible phosphorylation of serine, threonine and tyrosine residues by the interplay of
protein kinases and phosphatases plays a key role in regulating many different cellular …

PknB is a member of the newly discovered eukaryotic-like protein serine/threonine kinase
(PSTK) family of proteins. The pknB gene was cloned and expressed in Escherichia coli …

Background Plants represent an intricate and innovative source for the discovery of novel
