Abstract excerpt
The UDP-glucose dehydrogenase activity of Bacillus subtilis YwqF is regulated by reversible phosphorylation on a tyrosine residue. This reaction, which is catalyzed by the protein-tyrosine kinase YwqD, activates the enzyme, while dephosphorylation of phosphotyrosine-YwqF by the phosphotyrosine-protein phosphatase YwqE reduces its enzyme activity. Our kinetic data indicate that the phosphorylated and...
