Development of a camelid single-domain antibody-based antigen detection assay for the pan-specific diagnosis of active human and animal Trypanosoma brucei infections

Journal of Clinical Microbiology
Trypanosoma brucei infections cause African trypanosomiasis, also known as sleeping sickness in humans and nagana in animals, presenting a significant global health and economic burden, especially in sub-Saharan Africa.

Identification of different trypanosome species in the mid-guts of tsetse flies of the Malanga (Kimpese) sleeping sickness focus of the Democratic Republic of Congo

Parasites & Vectors, 2012
Background The Malanga sleeping sickness focus of the Democratic Republic of Congo has shown an epidemic evolution of disease during the last century. However, following case detection and treatment, the prevalence of the disease decreased considerably ...

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

FEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

The crystal structure of the Borrelia burgdorferi nicotinamidase BBE22 resolves a long‐standing annotation error

FEBS Open Bio, EarlyView.
The crystal structure of Borrelia burgdorferi nicotinamidase (PncA/BBE22) reveals the correct full‐length protein initiated from a non‐canonical AUU start codon. The structure validates previous biochemical findings and resolves a long‐standing annotation error, demonstrating that the truncated database sequence is structurally incompatible with the ...

Golgi-associated phosphohydrolases in Trypanosoma brucei brucei

Molecular and Biochemical Parasitology, 1997
Various parasitic protozoa of the family Trypanosomatidae such as Crithidia spp. [1]; Trypanosoma cruzi [2]; Leishmania donovani [3] and salivarian trypanosomes [4-8] have been shown to contain acid phosphatase activity (EC.3.1.3.2, orthophosphoric-monoester phosphohydrolase activity).

Transcripts enriched in codons that trigger P‐site tRNA‐mediated mRNA decay possess stable mRNA

FEBS Open Bio, EarlyView.
PTMD codons were first described by Mendel et al. as mediators of an mRNA decay pathway dependent on the human protein CNOT3, homologous to yeast Not5. Our findings confirm that PTMD codons destabilize transcripts; however, unlike in yeast, the human pathway specifically targets and slightly destabilizes primarily stable mRNAs.

Trypanosoma Brucei Aquaglyceroporins Facilitate the Uptake of Arsenite and Antimonite in a pH Dependent Way

Cellular Physiology and Biochemistry, 2013
Background: Trypanosoma brucei is a primitive parasitic protozoan that thrives in diverse environments such as the midgut of the tsetse fly and the blood of a mammalian host.

Turning Bonding Into Function: The Emerging Role of the Bioactive Selenium─Metal Motif in Toxicology and Medicinal Chemistry

Chemistry – A European Journal, EarlyView.
Balancing Act: Se─M bond serving as the fulcrum of the balance scale to compare the different weight of toxicity and therapeutic effects in biological environment. ABSTRACT The synthesis and characterization of organo‐selenium compounds have attracted considerable interest for decades, driven by the search for efficient catalysts and bioinspired ...

Increased Trypanosoma brucei cathepsin-L activity inhibits human serum-mediated trypanolysis

Microbial Cell, 2014
Most African trypanosomes, including the veterinary species Trypanosoma brucei brucei and T. congolense are susceptible to lysis by human serum. A recent study by Alsford et al. [PLoS Pathogens (2014) 10, e1004130] has identified a T. b. brucei lysosomal
