DNA-dependent RNA-directed protein synthesis in vitro, II. Synthesis of a phi-X-174 coat protein component

We present evidence to show that the primary protein product of an in vitro DNA-dependent RNA-directed protein-synthesizing system primed by varphiX-174 replicative form DNA comigrates in a gel electrophoresis system with a phage structural component. This protein component is precipitable by antiserum to purified phage.
