Synthesis of cyclic oligonucleotides by a modified phosphotriester approach.

abstract：:Two CTAG-recognizing restriction and modification (R/M) systems, designated MthZI and MthFI, were identified in the thermophilic archaeon Methanobacterium thermoformicicum strains Z-245 and FTF, respectively. Further analysis revealed that the methyltransferase (MTase) genes are plasmid-located in both strains. The pl...
