Abstract
SAMHD1 catalyses the dephosphorylation of deoxynucleotide triphosphates (dNTPs) and has antiretroviral activity. Here, the authors present the crystal structures of SAMHD1-oligonucleotide complexes, which reveal that the allosteric binding sites of SAMHD1 are plastic and can fit oligonucleotides in place of the two allosteric activators GTP and dNTP, and they also show that SAMHD1 recognises GpsN phosphorothioation modifications in nucleic acids, which is of interest in drug design.
