The Ribonucleic Acids of Crithidia fasciculata*
The Journal of Protozoology, 1978SYNOPSIS. Crithidia fasciculata ribosomes were found to be 80S and to dissociate into 58 and 41S subunits; on 5 to 50% sucrose gradients, rRNA was separated into 25, 18, and 5S components. The molecular sizes of the heavier rRNA species, estimated by polyacrylamide gel electrophoresis were 1.24 and 0.84 M (×106 daltons). The 25S RNA has a tendency to

Ectonucleotide diphosphohydrolase activity in Crithidia deanei
Parasitology Research, 2002In this work we describe the ability of living Crithidia deanei to hydrolyze extracellular ATP. In intact cells at pH 7.2, a low level of ATP hydrolysis was observed in the absence of any divalent metal (0.41+/-0.13 nmol P(i) h(-1) 10(7) cells(-1)). The ATP hydrolysis was stimulated by MgCl(2) and the Mg(2+)-dependent ecto-ATPase activity was 4.05+/-0 ...

Kinetoplast DNA of Crithidia*†
The Journal of Protozoology, 1974SYNOPSIS. The results of physiochemical and electron microscope studies on the structure of the kinetoplast DNA of Crithidia are discussed. The molecular weight of isolated kinetoplast DNA is approximately 41 × 109 daltons. The basic unit of organization of this DNA is a covalently closed circular molecule 0.8 μm in contour length (molecular weight 1 ...

Desmosomes and hemidesmosomes in the flagellate Crithidia fasciculata
Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1970The flagellum of the trypanosomatid flagellate Crithidia fasciculata expands asymmetrically as it emerges from the reservoir. Where the flagellar memhrane approaches the membrane lining the reservoir, desmosomes are found. These structures are arranged in several slightly curved lines and have many features in common with vertebrate desmosomes.

Cell surface charge and sugar residues of Crithidia fasciculata and Crithidia luciliae.
Microbios, 1992The surface charge of Crithidia fasciculata and Crithidia luciliae was analysed by measurement of the zeta-potential and labelling of the protozoan surface with cationized ferritin particles. Both trypanosomatids have a net negative surface charge, with a zeta-potential of -10.39 mV and -11.12 mV for C. luciliae and C. fasciculata, respectively. Enzyme
