Its mode of action seems to be along these lines. When the thin skin layers and mucus of the mouth, anus or vagina are damaged then, as in all cell damage, there is a large influx of white cells to combat any possible invaders. It is precisely this gathering of white cells, normally effective for killing off viruses or bacteria, that HIV (Human Immuno-deficiency Virus) attacks and takes over.

Figure 16.2 shows the results of comparisons of sequences of the aspartic proteinase family of enzymes. It includes pepsins from eukaryotic sources and pro-teinases from retroviruses like human immuno-deficiency virus, HIV. The retroviral proteinases consist of two identical subunits, whereas the pepsins have a single chain with two similar halves, the amino-terminal and the carboxyl-terminal domains, whose structures resemble each other and the subunits of the retroviral proteinases. The sequences of the two domains of the pepsins and the subunits of retroviral proteinases were aligned using COMPARER. Only three residues are identical in all the...

The causative agent of acquired immune deficiency syndrome (AIDS) is an enveloped virus (the human immuno-deficiency vims, HfV-1), a member of the retrovirus family (see Chapter 50 in this volume) [2]. An extensive part of the virion surface is predicted to be covered by carbohydrate as 50% of the molecular mass of the major envelope glycoprotein is carbohydrate in the form of oligosaccharide chains attached to the polypeptide backbone. 

AIDS (Acquired Immuno Deficiency Syndrome) poses a threat to India as a large number of people are infected with HTV (Human Immunodeficiency Virus). There are no drugs today for AIDS. The problem which has dogged anti- HIV drugs is that resistant mutant forms of virus are formed within mere weeks. Lot of research work is to be done in search of a vaccine against HIV.
