Expression of Campylobacter genes for proline biosynthesis in Escherichia coli

Abstract
Cloned DNA from Campylobacter jejuni was found to complement auxotropic defects in proline metabolism in several strains of Escherichia coli. A 4.4-kilobase fragment of Campylobacter DNA encodes the genes analogous to the proA and B genes of E. coli and Salmonella typhimurium.
