Abstract in another language
Replication complexes containing wild-type and RNase H-deficient p66/p51 human immunodeficiency virus type 1 reverse transcriptase(HIV-1 RT)were analyzed by DNase I and SI footprinting. While crystallography and chemical footprinting data demonstrate that 15-18 bases of primer and template occupy the DNA polymerase and RNase H active centers, enzymatic footprinting suggests that a larger portion of substrate is encompassed by the replicating enzyme. Independent of the position of DNA synthes is arrest, template nucleotides +7 to -23 and primer nucleotides -1 to -25 are nuclease resistant. On both DNA strands, position -20 remains accessible to DNase I cleavage, suggestive of an alteration in nucleic acid structure between exiting the RNase H catalytic center and leaving the C-terminal p66 domain. A model of HIV-1 RT containing an extended single-stranded template and duplex region was constructed on the basis of the structure of an RT/DNA complex. Mapping of footprint data onto this model shows consistency between biochemical and structural data, implicating a contribution from domains proximal to the catalytic centers.
