Isolation and expression of the Bradyrhizobium japonicum adenylate cyclase gene (cya) in Escherichia coli.
A 5.0-kilobase-pair HindIII fragment of Bradyrhizobium japonicum DNA containing the cya gene which encodes adenylate cyclase was isolated as an insert in pBR322, using marker rescue of the maltose-negative phenotype of an Escherichia coli cya mutant for identification. The isolated B. japonicum DNA fragment was capable of reversing the pleiotropic phenotype of cya mutations when inserted in either orientation in the HindIII site of pBR322. The complemented E. coli strains produced high levels of cyclic AMP. No sequence homology between the B. japonicum cya gene and that of E. coli was detected by hybridization analysis.
