Abstract

Thymine auxotrophs of Bacillus subtilis strains lysogenic for temperate bacteriophage SP beta c2 were transformed to prototrophy by DNA from related phage phi 3T. During transformation, the phi 3T-encoded thymidylate synthetase gene, thyP3, became integrated into the extreme right end of the SP beta c2 prophage near the bacterial citK gene. Upon heat induction, the transformed B. subtilis cells released SP beta c2T phages that could lysogenize thymine auxotrophs and convert them to prototrophy. Comparison of restriction endonuclease fragments of DNAs from SP beta c2 and SP beta c2T phages revealed that the latter contained a large region of deletion and substitution near the center of the chromosome. This region included the phage attachment site on the SP beta c2 genome.
