This study has developed Corynebacterium ammoniagenes (c. ammoniagenes) purine gene transcriptional reporters (purF-lacZ and purE-lacZ) that function in Escherichia coli (E. coli) DH5a. After transformation of a C. ammoniagenes gDNA library into E. coli cells harboring either purF-lacZ or purE-lacZ, C. ammoniagenes clones were obtained that repress purF-lacZ and purE-lacZ gene expression. The potential purE and purF regulatory genes are homologous to the genes encoding transcription regulators, the regulatory subunit of RNA polymerase, and genes for purine nucleotide biosynthesis of various bacteria.
