title: E. coli phosphofructokinase synthesized in vitro from a ColE1 hybrid plasmid.
abstract: A hybrid plasmid, pLC 16-4, from the ColE1-DNA (E. coli) bank of Clarke and Carbon (1976) carrying pfkA was used to program an in vitro protein synthesis system from E. coli. Phosphofructokinase was the main product, as determined by enzyme assay, immunoprecipitation and gel electrophoresis. The enzyme was synthesized in vitro without added cAMP at a rate (enzyme/genome/h) ca. 30% the in vivo value, a higher efficiency than usually found in cell free systems. The plasmic molecular weight is ca. 16.10(6) daltons.
