ST1710-DNA complex crystal structure reveals the DNA binding mechanism of the MarR family of regulators.

abstract：:LNA oligonucleotides constitute a class of bicyclic RNA analogues having an exceptionally high affinity for their complementary DNA and RNA target molecules. We here report a novel method for highly efficient isolation of intact poly(A)+ RNA using an LNA-substituted oligo(dT) affinity ligand, based on the increased af...
