Identification of a polyketide synthase coding sequence specific for anatoxin-a-producing Oscillatoria cyanobacteria.

ABSTRACT: We report the identification of a sequence from the genome of Oscillatoria sp. strain PCC 6506 coding for a polyketide synthase. Using 50 axenic cyanobacteria, we found this sequence only in the genomes of Oscillatoria strains producing anatoxin-a or homoanatoxin-a, indicating its likely involvement in the biosynthesis of these toxins.
