Secondary promoter of the guanine operon of Escherichia coli K-12.
Evidence of a secondary promoter for the guaA gene within the guaB gene was obtained by using lambdapguaA transducing phage. The technique is generally applicable to distinguish a promoter present within a bacterial deoxyribonucleic acid segment, which has replaced the lambda b2 region of transducing phage, from the phage pI promoter.
