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.
我们报告了从颤藻属(Oscillatoria sp.)菌株PCC 6506基因组中鉴定出一段编码聚酮合酶的序列。利用50种无菌蓝细菌,我们发现该序列仅存在于产生anatoxin-a或homoanatoxin-a的颤藻菌株基因组中,这表明它可能参与了这些毒素的生物合成。
