The human APOBEC3G (apolipoprotein B messenger-RNA-editing enzyme, catalytic polypeptide-like 3G) protein is a single-strand DNA deaminase that inhibits the replication of human immunodeficiency virus-1 (HIV-1), other retroviruses and retrotransposons. APOBEC3G anti-viral activity is circumvented by most retroelements, such as through degradation by HIV-1(More)
Bacteriophage DNA packaging motors translocate their genomic DNA into viral heads, compacting it to near-crystalline density. The Bacillus subtilis phage 29 has a unique ring of RNA (pRNA) that is an essential component of its motor, serving as a scaffold for the packaging ATPase. Previously, deletion of a three-base bulge (18-CCA-20) in the pRNA A-helix(More)
APOBEC3G is the best known of several DNA cytosine deaminases that function to inhibit the replication of parasitic genetic elements including the lentivirus HIV. Several high-resolution structures of the APOBEC3G catalytic domain have been generated, but none reveal how this enzyme binds to substrate single-stranded DNA. Here, we constructed a panel of(More)
