Purine nucleoside phosphorylase from Schistosoma mansoni in complex with ribose-1-phosphate
Schistosomes are blood flukes which cause schistosomiasis, a disease affecting approximately 200 million people worldwide. Along with several other important human parasites including trypanosomes and Plasmodium, schistosomes lack the de novo pathway for purine synthesis and depend exclusively on the salvage pathway for their purine requirements, making the latter an attractive target for drug ...
متن کاملSpecificity of Mouse Uridine Phosphorylase*
Two distinct pyrimidine nucleosidases, isolated from Escheri&a coli, show complete specificity for the pentose moiety of the nucleoside. Pyrimidine deoxyribonucleoside phosphorylase (1) shows complete specificity for the deoxyribosyl group, and uridine phosphorylase (2) for the ribosyl group. Mammalian uridine phosphorylase preparations (3, 4), however, have appreciable deoxyuridine phosphoryla...
متن کاملCrystal Structure of Schistosoma mansoni Adenosine Phosphorylase/5’-Methylthioadenosine Phosphorylase and Its Importance on Adenosine Salvage Pathway
Schistosoma mansoni do not have de novo purine pathways and rely on purine salvage for their purine supply. It has been demonstrated that, unlike humans, the S. mansoni is able to produce adenine directly from adenosine, although the enzyme responsible for this activity was unknown. In the present work we show that S. mansoni 5´-deoxy-5´-methylthioadenosine phosphorylase (MTAP, E.C. 2.4.2.28) i...
