Cloning of the Vibrio harveyi luciferase genes: use of a synthetic oligonucleotide probe


A mixed-sequence synthetic oligonucleotide probe was used to isolate a clone containing the gene encoding the alpha subunit of bacterial luciferase from Vibrio harveyi and part of the gene coding for the beta subunit. DNA sequence analysis has allowed us to determine that the genes are closely linked on the bacterial chromosome and transcribed in the same direction. Comparison of the sequences in the regions preceding the two structural genes has revealed considerable homology and has identified sites that may be involved in the expression of the genes. Identification of a clone from a clone bank of total genomic DNA from this organism shows that mixed probes can be successfully used to isolate a gene of interest from any bacterium provided some protein sequence for the gene product is available.
