In biochemistry, a kinase is an enzyme that catalyzes the transfer of phosphate groups from high-energy, phosphate-donating molecules to specific process is known as phosphorylation, where the substrate gains a phosphate group and the high-energy ATP molecule donates a phosphate group. This transesterification produces a phosphorylated substrate and ADP. Scientists at NIAID have shown how the OH7 strain of Escherichia coli causes infection and thrives by manipulating the host immune response. The bacterium secretes a protein called NleH1 that.

effect of chlorpromazine on protein phosphorylation in Escherichia coli by Mohammed Sebaihia Download PDF EPUB FB2

More than 40 protein species including RNA polymerase were found to be phosphorylated in Escherichia coli on analyses of 32P-labeled cell lysates by single and two-dimensional gel electrophoresis and autoradiography.

The protein species and the level of phosphorylation varied depending on the cell growth phase. Obviously a better understanding of the func- tional link between protein phosphorylation and the SOS response necessitates prior identifi- cation of the relevant phosphoproteins.
