== Publication Abstract from PubMed == | |||
Tenofovir is an acyclic phosphonate analog of deoxyadenylate used in AIDS and hepatitis B therapy. We find that tenofovir diphosphate, its active form, can be produced by human nucleoside diphosphate kinase (NDPK), but with low efficiency, and that creatine kinase is significantly more active. The 1.65 A x-ray structure of NDPK in complex with tenofovir mono- and diphosphate shows that the analogs bind at the same site as natural nucleotides, but in a different conformation, and make only a subset of the Van der Waals and polar interactions made by natural substrates, consistent with their comparatively low affinity for the enzyme. | |||
