Oligonucleotide probes for bacterial acylcarrier protein genes.
Using a recently-introduced rapid manual method, we have synthesized a family of thirty six individual oligonucleotides of unique sequence (18-mers), which correspond to the conserved amino acid sequence, GADSLD, found at the 4'-phosphopantetheine-binding site of the acylcarrier component of bacterial and plant fatty acid synthases. Hybridisation of each of these oligonucleotides to Southern blots of restricted Streptomyces erythreus DNA under stringent conditions showed that (i) only two probes hybridised specifically, (ii) neither probe hybridised to more than one sequence, and (iii) each probe apparently recognised a different DNA sequence. In the same synthesis, ninety-two other oligonucleotides (15-18-mers) were also constructed, mostly in yields of 2-10%.
