Phosphorothioated dna
Webgenus Streptomyces that cleaves methylated and phosphorothioated (S-modified) DNA that has a non-bridging oxygen of the phosphate group in the DNA backbone replaced by sulfur. The DNA S-modification is sequence specific, and a dnd (DNA degradation) gene cluster encoding four or five proteins is responsible for the S-modification [6,7].
