A reverse transcriptase ribozyme
A highly evolved RNA polymerase ribozyme was found to also be capable of functioning as a reverse transcriptase, an activity that has never been demonstrated before for RNA. This activity is thought to have been crucial for the transition from RNA to DNA genomes during the early history of life on Earth, when it similarly could have arisen as a secondary function of an RNA-dependent RNA polymer...
متن کاملNucleotide Reverse Transcriptase Inhibitors
4 Optimal HIV-1 suppression often is difficult to achieve and maintain with currently available antiretroviral drugs, and viral resistance eventually emerges to many drugs. Chronic antiretroviral therapy is also associated with complications such as body fat redistribution, hypertriglyceridemia and hypercholesterolemia, abnormal glucose metabolism, lactic acidosis, pancreatitis, avascular necro...
متن کاملNucleoside Reverse Transcriptase Inhibitors
Although the incidence of HIV infection among women is increasing, the proportion of women in clinical trials that evaluate interventions for the treatment of HIV infection and its complications has historically been lower than the proportion of women in the HIV/AIDS patient population. Therefore, most knowledge about the efficacy of antiretroviral drugs and the adverse reactions associated wit...
متن کاملA New Take on Telomerase Reverse Transcriptase
The role of telomeres in maintaining genetic stability was first described by Blackburn1 in 1991. Telomeres and their associated proteins provide protection against DNA degradation because 40 to 200 bp of the telomere’s tandem repeats are lost on each successive cell division, resulting in the progressive shortening of chromosomes. Telomeres also help to regulate the “cellular clock” because cr...
متن کاملHuman Immunodeficiency Virus Reverse Transcriptase
3’-Azido-3’-deoxythymidine 5’4riphosphate (AZTTP) was an efficient substrate for the human immunodeficiency virus 1 reverse transcriptase. It was incorporated into both homopolymer and defined sequence DNA-primed RNA templates and DNA-primed DNA templates. The substrate and inhibitor kinetics of both AZTTP and dTTP were dependent on the template-primer and reaction conditions used. dTMP was inc...
