ATP-dependent Protein Kinases in Bacteria


ATP-dependent Protein Kinases in Bacteria

A J Cozzone. J Cell Biochem. .


Protein phosphorylation has been shown to occur in over fifty different bacterial species and, therefore, seems to be a universal device among prokaryotes. Most of the protein kinases responsible for this modification of proteins share the common property of using adenosine triphosphate as phosphoryl donor. However, they differ from one another in a number of structural and functional aspects. Namely, they exhibit a varying acceptor amino acid specificity and can be classified, on this basis, in three main groups: protein-histidine kinases, protein-serine/threonine kinases and protein-tyrosine kinases.
