Dianthin antiviral protein (DAP) is a naturally occurring antiviral, protein from the leaves of carnation (Dianthus caryophyllus) capable of, depurinating HIV-1 RNA and inhibiting HIV-1 replication in human, peripheral blood mononuclear cells. Escherichia coli-derived recombinant, DAP (rDAP, amino acids 1-254) was purified to homogeneity for structural, and functional studies. In the following paper the X-ray crystal structure, of rDAP as well as its complexes with cyclic AMP and adenyl-guanosine, (ApG) as substrate analogs at 1.7 A resolution are reported. Molecular, modeling studies of the interactions of DAP and the structurally similar, pokeweed antiviral protein (PAP) with a single-stranded RNA heptamer, predicted a more potent anti-HIV activity for rDAP due to its unique, surface topology and more favorable charge distribution in its 20 A-long, RNA binding active center cleft. In accordance with the predictions of the, modeling studies, rDAP was more potent than rPAP in depurinating HIV-1, RNA. To the knowledge of the authors, this is the first structural and, functional characterization of recombinant DAP.
