Synthesis of an ovalbumin-like protein by Escherichia coli K12 harbouring a recombinant plasmid.

A cloned DNA transcript of ovalbumin mRNA was cut a few nucleotides away from the initiator codon, and fused in phase to the beginning of the Escherichia coli beta-galactosidase gene. The hybrid gene has been cloned in E. coli where it produces large amounts of an ovalbumin-like protein.
