Isolation and characterization of kinetoplast DNA from bloodstream form of Trypanosoma brucei
We have used restriction endonucleases PstI, EcoRI, HapII, HhaI, and S1 nuclease to demonstrate the presence of a large complex component, the maxi-circle, in addition to the major mini-circle component in kinetoplast DNA (kDNA) networks of Trypanosoma brucei (East African Trypanosomiasis Research Organization [EATRO] 427). Endonuclease PstI and S1 nuclease cut the maxi-circle at a single site,...
متن کاملDepletion of mitochondrial acyl carrier protein in bloodstream-form Trypanosoma brucei causes a kinetoplast segregation defect.
Like other eukaryotes, trypanosomes have an essential type II fatty acid synthase in their mitochondrion. We have investigated the function of this synthase in bloodstream-form parasites by studying the effect of a conditional knockout of acyl carrier protein (ACP), a key player in this fatty acid synthase pathway. We found that ACP depletion not only caused small changes in cellular phospholip...
متن کاملTranscription of kinetoplast DNA in Trypanosoma brucei bloodstream and culture forms.
Kinetoplast DNA is the unusual mitochondrial DNA of trypanosomes. In Trypanosoma brucei it consists of about lo* minicircles (0.3 km) and lo* maxicircles (6 pm) catenated into a single network. The maxicircles are probably the equivalent of mitochondrial DNA in other organisms. Here we report that a fraction of the total cellular RNA from bloodstream form and culture form T. brucei hybridizes w...
متن کاملRole of p38 in replication of Trypanosoma brucei kinetoplast DNA.
Trypanosomes have an unusual mitochondrial genome, called kinetoplast DNA, that is a giant network containing thousands of interlocked minicircles. During kinetoplast DNA synthesis, minicircles are released from the network for replication as theta-structures, and then the free minicircle progeny reattach to the network. We report that a mitochondrial protein, which we term p38, functions in ki...
متن کاملLipidomic analysis of bloodstream and procyclic form Trypanosoma brucei.
The biological membranes of Trypanosoma brucei contain a complex array of phospholipids that are synthesized de novo from precursors obtained either directly from the host, or as catabolised endocytosed lipids. This paper describes the use of nanoflow electrospray tandem mass spectrometry and high resolution mass spectrometry in both positive and negative ion modes, allowing the identification ...
