| Abstract: | A 1650 base pair (BP) fragment carrying the entire argF structural gene with its associated control regions was isolated from an EcoRI/BamHI digest of phi80argFilambda cI857 DNA. This segment was cloned using the EcoRI and BamHI cleavage sites in the plasmid pBR322. A preliminary restriction map of the argF region was prepared. RNA polymerase binding studies indicated that the argF promoter is located approx. 30 base pairs from the EcoRI terminus of the cloned DNA segment. |
