Phosphorothioated dna bases
WebJul 4, 2024 · The sulfur atom of phosphorothioated DNA (PT-DNA) is coordinated by a surface cavity in the conserved sulfur-binding domain (SBD) of type IV restriction enzymes. However, some SBDs cannot recognize the sulfur atom in some sequence contexts. Webcompared to the fully phosphorothioated product (Figure 9).
