UMP synthesis in the kinetoplastida

Biochimica et Biophysica Acta (BBA) - General Subjects, 1982
All six enzymes of pyrimidine biosynthesis de novo have been detected in homogenates of the culture promastigote form of Leishmania mexicana amazonensis, the blood trypomastigote form of Trypanosoma brucei and the culture epimastigote, blood trypomastigote and intracellular amastigote forms of Trypanosoma cruzi.

The glycosomes of the Kinetoplastida

Biochimie, 1993
Glycosomes are the microbodies of the organisms belonging to the order of the Kinetoplastida, comprising trypanosomes and leishmanias, both pathogens to man. The organelles sequester a number of glycolytic enzymes that are normally located in the cytosol in other eukaryotic organisms, and share some enzymes with peroxisomes and glyoxysomes of other ...

Genetic Manipulation of Kinetoplastida

Parasitology Today, 1999
During the 1980s, many kinetoplastid genes were cloned and their function inferred from homology with genes from other organisms, location of the corresponding proteins or expression in heterologous systems. Up until 1990, before the availability of DNA transfection methodology, we could not analyze the function of kinetoplastid genes within the ...

Proliferative opisthomastigote forms in Herpetomonas roitmani (Kinetoplastida: Trypanosomatidae)

Parasitology Research, 1996
The flagellate Herpetomonas roitmani is a symbiont-bearing trypanosomatid that spontaneously differentiates from promastigote to para- and opisthomastigote forms when maintained in axenic culture medium. Thus, after cultivation for 72 h at 28 degrees C, 37% of the total number of cells are in the opisthomastigote form.

Structure, function, and biogenesis of glycosomes in Kinetoplastida

Journal of Bioenergetics and Biomembranes, 1994
Glycosomes are intracellular, microbody-like organelles found in all members of the protist order Kinetoplastida examined. Nine enzymes involved in glucose and glycerol metabolism are associated with these organelles. These enzymes are involved in pathways which, in other organisms, are usually located in the cytosol.

Kinetoplastidae display naturally occurring ancillary DNA-containing structures

Molecular and Biochemical Parasitology, 1994
Kinetoplast-derived, DNA-containing structures were found in several members of the order Kinetoplastida. The structures, for which we propose the name ancillary DNA-containing structures (aDNA), were discovered during the course of low-light-level video fluorescence microscopy studies using several nucleic acid-specific fluorescent reagents.

Polymorphism in the subtelomeric regions of chromosomes of Kinetoplastida

Transactions of the Royal Society of Tropical Medicine and Hygiene, 2002
Leishmania spp. and the related kinetoplastid Trypanosoma brucei are single-celled parasites. In Leishmania, the nuclear genome comprises 36 diploid chromosomes and occasional amplified minichromosomes, while the T. brucei nucleus contains 11 larger diploid chromosomes and a variable number of intermediate-sized and minichromosomes.

The cell surface charge of Bodo sp. (Kinetoplastida: Bodonidae)

European Journal of Protistology, 1993
Cytochemistry, using cationized ferritin particles at pH 7.2 and colloidal iron particles at pH 1.8, and cell electrophoresis were used to analyze the surface charge of the protozoan Bodo sp. Surface anionic sites are homogeneously distributed throughout the protozoan surface, including the flagella, the cytostome and the flagellar pocket.

Hydroxyurea-Induced Synchrony of DNA Replication in the Kinetoplastida

Experimental Cell Research, 1994
We have developed a reliable and reproducible method to induce synchrony of the DNA synthetic cycle in the Kinetoplastida. The method involves treatment of cultures with 20 mM hydroxyurea (HU) and fetal bovine serum. Both stationary-phase and exponential-phase cultures can be synchronized.

Freeze‐fracture study of Bodo sp. (Kinetoplastida: Bodonidae)

Microscopy Research and Technique, 1995
AbstractFreeze‐fracture technique was used to analyse the structure of conventionally fixed and quickly frozen Bodo sp., a free‐living kinetoplastid. In the former method, chemically fixed and cryopreserved cells presented a corrugated membrane pattern in the flagella and cell body surfaces.
