Phosphorylation of myosin light chain at distinct sites and its association with the cytoskeleton during enteropathogenic Escherichia coli infection.
Myosin light chain, the most prominent host cell phosphoprotein during adhesion of enteropathogenic Escherichia coli to cultured HEp-2 cells, was shown to be distributed between cytosolic and cytoskeletal cell fractions; its association with the cytoskeletal fraction increased with time of enteropathogenic E. coli incubation. Phosphopeptide mapping indicated cytosolic and cytoskeletal myosin light chain phosphorylation at different sites by protein kinase C and myosin light chain kinase.
