This unicellular protozoan is a eukaryotic intracellular parasite that is subject to tryptophan limitation by exactly the same host mechanism used against the chlamydiae.
Reversible protein phosphorylation is gaining recognition as a potentially important mechanism of post-translational regulation in protozoan parasites, especially those belonging to the Apicomplexan family.

To address these issues, we have characterized the RNA triphosphatases of two other fungi, including the human pathogen Candida albicans and the fission yeast Schizosaccharomyces pombe [ 10 11 12 ] . The fungal triphosphatases, S. cerevisiae Cet1, C. albicans CaCet1 and S. pombe Pct1, belong to a new family of metal-dependent phosphohydrolases that embraces the triphosphatase components of DNA virus and protozoan mRNA capping systems [ 1 7 13 14 ] . The defining features of the metal-dependent RNA triphosphatases are two glutamate-containing motifs that are required for catalysis and comprise the metal-binding site in the crystal structure of S. cerevisiae Cet1.
Since human infection with Cryptosporidium parvum was first documented in 1976 [ 1 ] , this protozoan parasite has been recognized worldwide as a major cause of diarrheal disease in humans [ 2 ] . In healthy, immunocompetent persons, C. parvum causes a self-limited diarrheal illness (cryptosporidiosis); however, in persons with severe immunosuppression, particularly those infected with the human immunodeficiency virus (HIV) and who have developed acquired immunodeficiency syndrome (AIDS), the diarrhea can be prolonged, severe, and life-threatening [ 3 4 ] . Currently there are no effective chemotherapeutic agents against cryptosporidiosis [ 5 ] . Cryptosporidium oocysts are found in the feces of infected humans, livestock, and wild animals [ 6 ] . Humans acquire the infection through person-to-person or animal-to-person contact, ingestion of fecally-contaminated water or food, or contact with fecally-contaminated environmental surfaces [ 7 ] .
