Carbohydrate Composition of Variant‐Specific Surface Antigen Glycoproteins from Trypanosoma brucei

The Journal of Protozoology, 1977
SYNOPSIS. The carbohydrate of variant‐specific surface antigen glycoproteins from bloodstream forms of 13 cloned variants of Trypanosoma brucei was analyzed by gas‐liquid chromatography. The glycoproteins contained from 6 to 17% carbohydrate by weight, and all contained the same 4 sugars: mannose, galactose, glucose, and glucosamine (probably as N ...

Trypanosoma brucei brucei: Variability in the association of some variant surface glycoproteins

Experimental Parasitology, 1988
In our isolation procedure, the surface antigens of the variants AnTat 1.1 and 1.10 (Trypanosoma brucei brucei) are essentially obtained as a disulfide-linked dimer while the AnTat 1.8 surface antigen is found as a mixture of monomer and disulfide-linked dimer.

Trypanosoma brucei: Conserved sequence organization 3′ to telomeric variant surface glycoprotein genes

Experimental Parasitology, 1989
We have previously postulated that telomeric variant surface glycoprotein (VSG) genes in Trypanosoma brucei serve more frequently than intrachromosomal VSG genes as basic copies for gene conversion. To examine this further we determined the sequence for approximately 1200 nucleotides 3' to the telomeric IsTat 1 VSG gene, expressed in early variant ...

Endocytosis and intracellular occurrence of the variant surface glycoprotein in Trypanosoma congolense

Journal of Ultrastructure and Molecular Structure Research, 1988
Trypanosoma congolense bloodstream forms were examined for binding sites of polyclonal anti-variant surface glycoprotein (VSG) antibodies using immunoelectron microscopy. Besides the surface, the antibodies labeled intracellular vesicles, the tubular membrane system, secondary lysosomes, and the digestive vacuole. Protein A gold (PAG), peroxidase gold (

Structure of the variant glycoproteins and surface coat of Trypanosoma brucei

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1984
The pathogenic African trypanosomes have a unique mechanism for antigenic variation. Each cell is covered by a surface coat consisting of about seven million essentially identical glycoprotein molecules drawn from a large repertoire of variants, each encoded by an individual gene.
