Disease relevance of Crithidia

 

High impact information on Crithidia

  • Localization of a type II DNA topoisomerase to two sites at the periphery of the kinetoplast DNA of Crithidia fasciculata [6].
  • To determine the structural features responsible for the curvature of kinetoplast DNA, we studied 13 adenine tracts in Crithidia fasciculata kinetoplast DNA [7].
  • In the presence of functional RT (from human L1, yeast Tyl or Crithidia CRE1), and in the absence of homologous recombination, an HO endonuclease-induced DSB at the mating type (MAT) locus is the primary site at which a marked cDNA is observed among surviving cells [8].
  • Although the COIII gene encoding cytochrome c oxidase subunit III in Trypanosoma brucei is edited along its entire length, the presumably homologous genes in two related trypanosomes, Leishmania tarentolae and Crithidia fasciculata, are only modestly edited at their 5' ends [9].
  • The cofactor was purified from the insect trypanosomatid Crithidia fasciculata and identified as a novel glutathione-spermidine conjugate, N1,N8-bis(L-gamma-glutamyl-L-hemicystinyl-glycyl)spermidine, for which the trivial name trypanothione is proposed [10].
 

Biological context of Crithidia

 

Anatomical context of Crithidia

  • A DNA polymerase beta in the mitochondrion of the trypanosomatid Crithidia fasciculata [16].
  • Crithidia fasciculata cells incubated with [14C]glucose or membranes derived from the same protozoan incubated with GDP-[14C]mannose were found to synthesize a lipid monophosphate mannose [17].
  • We discovered that topoisomerase II catalytic activity in 1.0 M NaCl nuclear extracts from the HL-60/MX2 variant, as measured by the decatenation of Crithidia fasciculata kinetoplast DNA, was reduced 4- to 5-fold compared to that in the parental HL-60 cells [18].
  • Pyruvate kinases of Crithidia luciliae and of Leishmania major, two trypanosomatids which are like T. brucei in containing glycosomes, were also stimulated by fructose 2,6-bisphosphate and inhibited by phosphate [19].
  • 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 [20].
 

Associations of Crithidia with chemical compounds

  • To identify proteins associated with the condensed form of kDNA in the cell, proteins were reversibly crosslinked to kDNA in whole cells of Crithidia fasciculata by formaldehyde treatment [21].
  • Cells of the insect parasite Crithidia fasciculata incubated with [14C]glucose were found to possess only one lipid-bound oligosaccharide with solubility in chloroform/methanol/water mixtures and net charge similar to the charges of dolichol pyrophosphate derivatives [22].
  • A Crithidia fasciculata single-stranded DNA-binding protein interacts specifically with the guanine-rich heavy strand of this origin-associated sequence (Y. Tzfati, H. Abeliovich, I. Kapeller, and J. Shlomai, Proc. Natl. Acad. Sci. USA 89:6891-6895, 1992) [23].
  • In Crithidia luciliae, this 3'-nucleotidase/nuclease previously has been shown to be highly regulated as purine and/or Pi starvation of this trypanosomatid leads to as much as a 1000-fold increase in enzyme activity [24].
  • Incubation of Crithidia fasciculata cells with [U-14C] glucose led to the synthesis of Man-P-dolichol but not of Glc-P-dolichol [25].
