On the chromatin structure of Trypanosoma cruzi
Molecular and Biochemical Parasitology, 1980The chromatin structure of Trypanosoma cruzi was investigated. It was found that, as in other eukaryotes, the chromatin is organized in repeating units, the nucleosomes containing about 200 base pairs of DNA associated with histones. While there is no difference in the DNA size in nucleosomes from T.

Chapter 7 Glycobiology of Trypanosoma cruzi
2009Abstract The glycobiology of Trypanosoma cruzi, the causative agent of Chagas' disease, has contributed significantly to the identification of target enzymes responsible for the construction of unique cell‐surface molecules. The authors discuss the structure of glycoinositolphospholipids, both free and as protein anchors in T. cruzi.

The Development of Trypanosoma cruzi in Triatominae
Parasitology Today, 2000Trypanosoma cruzi multiplies and differentiates in the digestive tract of triatomine insects. These insects ingest an enormous amount of blood, with ingestion followed very rapidly by a strong diuresis, slow digestion and occasionally long periods of starvation.

The γ-glutamyltranspeptidase of Trypanosoma cruzi
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1987Trypanosoma cruzi epimastigotes show gamma-glutamyltranspeptidase activity which has characteristics significantly different than the mammalian enzyme. The protozoan enzyme is localized in the cytosolic fraction, it has a Km of 1.6 mM and a Vmax of 17.4 nmol/min/mg protein with L-gamma-glutamyl-p-nitroanilide as gamma-glutamyl donor, and an optimun pH ...

Characterization of Trypanosoma cruzi telomerase
Acta Tropica, 2011High telomerase activity is always associated with actively dividing cells, however the detection of this activity in dividing Leishmania and Trypanosoma cruzi cells has always been disappointingly low. Recently, we have found that Leishmania major telomerase activity can be activated by heat, which combined with dilutions of the nuclear extracts ...

Struvite Precipitation by Trypanosoma cruzi
The Journal of Parasitology, 1987It has been previously reported that some microorganisms in culture possess the capacity to generate exocellular mineral crystals. Some species of bacteria are able to produce crystals such as aragonite, calcite, apatite, stroncianite, and struvite (Greenfield, 1963, Annals of the New York Academy of Science 109: 23-45; Ennever et al., 1974, Journal of

Catabolic metabolism in Trypanosoma cruzi
International Journal for Parasitology, 1980Abstract Culture, blood and intracellular forms of Trypanosoma cruzi have a high rate of endogenous oxygen uptake and probably utilize amino acids and carbohydrates as their exogenous energy sources. It is likely that triglyceride is the main energy reserve. Oxidation of carbohydrate by all forms is probably via a glycolytic sequence and a complete

Heme synthetase in Trypanosoma cruzi
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1986Heme-synthetase (Heme-S) has been studied in the epimastigote form of T. cruzi (Tulahuen and Y strains). The enzyme is confined to the "mitochondrial" fraction (sedimented at 30,000 g). Activity was dependent on protein and time of cell storage. Enzymic proto- and meso-heme formation was inhibited up to 40 and 72% respectively by Triton X-100.

Fatty acids of Trypanosoma cruzi
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 19821. The fatty acid pattern of total lipids from T. cruzi is different from one of its growth medium. 2. The distribution of major fatty acids in phospholipid fraction was linoleic (50.4%), oleic (25.6%), stearic (10.1%) and palmitic (6.3%) and in neutral lipid fraction oleic and linolelc (about 29% each), palmitic (18.3%) and stearic (9.8%). 3.
