Abstract

In the 70's Senft and coworkers published a series of articles demonstrating that S. mansoni was unable to incorporate both glycine and glucose in the purine ring indicating the lack of a "de novo" purine pathway in the parasite and highlighting its dependence on imported host's purine . Genes coding for all purine salvage enzymes were found in the S. mansoni genome. In S. mansoni, the purine salvage pathway is composed of 18 enzymes (five of them represent different isoforms of the same protein), in three different sub-pathways for conversion of adenosine to AMP or GMP. Given the importance of the purine salvage pathway for parasite metabolism, we are currently undertaking a systematic approach to investigating the structural biology and kinetics of the enzymes involved.It is expected that this knowledge will provide a more rational basis for target selection in the future. Specifically, this knowledge is necessary in order to understanding the ways in which the parasite could be selectively starved of resources, which could be used to develop new drugs and/or vaccines against this important human parasite.
