Abstract

A fragment of the Dictyostelium discoideum myosin heavy chain gene representing heavy meromyosin was coexpressed in Escherichia coli with the entire essential myosin light chain from the scallop. The expressed myosin heavy chain and essential myosin light chain copurify through ammonium sulfate fractionation, anion exchange, and gel filtration chromatography. The purified complex consists of about 1 mol of light chain per mol of heavy chain. This stoichiometry, which is that of native myosin, suggests that no special eukaryotic machinery is required for coassembly of these two proteins. By coexpressing different myosin heavy chain and myosin light chain combinations, it should be possible to study various isoforms of these two proteins, which are both products of multigene families in mammals. E. coli is thus an ideal system in which to study expression and multimeric assembly of individual components of the eukaryotic contractile apparatus.
