Characterization Of Human T-Cell Leukemia Virus 1 Reverse Transcriptase, Pinky Gundayao Agbuya

Theses and Dissertations in Biomedical Sciences
Human T-cell leukemia virus 1 (HTLV-1) is a type C human retrovirus which has been the causative agent of Adult T-cell leukemia. Replication of the retrovirus; requires a reverse transcriptase which converts the retroviral RNA into DNA which is later incorporated into the host's genome. Very little is known about the reverse transcriptase of HTLV-1. Researchers have attempted to purify HTLV-1 RT by isolating the enzyme from human cell lines. Because large amounts of protein could not be produced by this isolation method, the reverse transcriptase cannot be fully characterized. In this research, a recombinant protein expressed in E. coli …

Structure-Substrate Binding Relationships Of Hiv-1 Reverse Transcriptase, Steve Chien-Wen Huang
Theses and Dissertations in Biomedical Sciences
Human Immunodeficiency Virus, type 1 (HIV-1), is the causative agent of the Acquired Immunodeficiency Syndrome (AIDS). HIV-1 reverse transcriptase (RT), a heterodimer p66/p51, has been the major target for treatment of AIDS. The significance of the p51 subunit and the RNase H domain of p66 in terms of their influence on the RNA-dependent DNA synthesis was investigated. Clones of the wildtype HIV-1 RT subunits, p66 and p51, and a recombinant C-terminal deletion mutant, p64, [Barr, P. J. (1987) Bio/Technoloav 5, 486-489] were employed to study the structure-substrate binding relationships of HIV-1 RT. The activity assays of RNA-dependent DNA synthesis on …
