Decreased processivity of human immunodeficiency virus type 1 reverse transcriptase (RT) containing didanosine-selected mutation Leu74Val: a comparative analysis of RT variants Leu74Val and lamivudine-selected Met184Val.

Abstract excerpt

We previously showed that a didanosine-selected mutation in pNL4-3 background conferred a replication disadvantage on human immunodeficiency virus type 1, resulting in a loss of replication fitness. This work has been extended by showing that a recombinant virus with the HXBc2 backbone and reverse transcriptase (RT) fragments from pNL4-3 containing the Leu74Val mutation produce decreasing amounts of p24 antigen...
