Bisphosphonates are potent inhibitors of Trypanosoma cruzi farnesyl pyrophosphate synthase.
We report the cloning and sequencing of a gene encoding the farnesyl pyrophosphate synthase of Trypanosoma cruzi. The protein (T. cruzi farnesyl pyrophosphate synthase, TcFPPS) is an attractive target for drug development, since the growth of T. cruzi is inhibited by carbocation transition state/reactive intermediate analogs of its substrates, the nitrogen-containing bisphosphonates currently i...
متن کاملThe Trypanosoma brucei sphingolipid synthase, an essential enzyme and drug target.
Sphingolipids are important components of eukaryotic membranes, particularly the plasma membrane, and are involved in a diverse array of signal transduction processes. In the Eukaryota the biosynthetic pathway for the formation of these lipid species is largely conserved. However, in contrast to mammals which produce sphingomyelin (SM), several pathogenic fungi and protozoa synthesize inositol ...
متن کاملThe cAMP-specific phosphodiesterase TbPDE2C is an essential enzyme in bloodstream form Trypanosoma brucei.
Chemotherapy of human sleeping sickness, a fatal disease caused by the protozoan parasite Trypanosoma brucei, is in a dismal state, and the identification and characterization of new drug targets is an urgent prerequisite for an improvement of the dramatic situation in the field. Over the last several years, inhibitors of cyclic nucleotide-specific phosphodiesterases have proven to be highly su...
متن کاملAn Essential Farnesylated Kinesin in Trypanosoma brucei
Kinesins are a family of motor proteins conserved throughout eukaryotes. In our present study we characterize a novel kinesin, Kinesin(CaaX), orthologs of which are only found in the kinetoplastids and not other eukaryotes. Kinesin(CaaX) has the CVIM amino acids at the C-terminus, and CVIM was previously shown to be an ideal signal for protein farnesylation in T. brucei. In this study we show K...
متن کاملThe myo-inositol-1-phosphate synthase gene is essential in Trypanosoma brucei.
The de novo synthesis of myo-inositol occurs via a two-step process: first, glucose 6-phosphate is converted into inositol 1-phosphate by an INO1 (myo-inositol-1-phosphate synthase; EC 5.5.1.4); then, it is dephosphorylated by an inositol monophosphatase. The myo-inositol can then be incorporated into PI (phosphatidylinositol), which is utilized in a variety of cellular functions, including the...
