Abstract
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.
