Glycobiology of Leishmania donovani.
Leishmania donovani, the causative organism of visceral leishmaniasis (VL) is one of the deadliest of the entire known Leishmania species. This protozoan parasite displays immense adaptability to survive under extremely harsh conditions. Cell surface glycoconjugates play a pivotal role in parasite virulence and infectivity. This review mainly highlights on the importance of these molecules and ...
متن کاملIsolation, characterization and expression of a cyclin from Leishmania donovani.
We have cloned and sequenced a DNA fragment (approximately 1 kb) containing a complete open reading frame from a cDNA library of Leishmania donovani promastigotes. The alignment of the derived polypeptide sequence and the modeling studies revealed that the protein is highly homologous to the mammalian cyclins having conserved cyclin box and substrate-docking motif. Northern blot analysis of the...
متن کاملBiochemical and biophysical characterization of Leishmania donovani gamma-glutamylcysteine synthetase
γ-glutamylcysteine synthetase (Gcs) is a vital enzyme catalyzing the first and rate limiting step in the trypanothione biosynthesis pathway, the ATP-dependent ligation of L-Glutamate and L-Cysteine to form gamma-glutamylcysteine. The Trypanothione biosynthesis pathway is unique metabolic pathway essential for trypanosomatid survival rendering Gcs as a potential drug target. Here we report the c...
متن کاملPhosphoglycosylation of a secreted acid phosphatase from Leishmania donovani.
The secreted acid phosphatase (SAcP) of L.donovani is a heterogeneous glycoprotein that displays a wide array of N- and O-linked glycosylations. The O-linked sugars are of particular interest due to their similarity to the phosphoglycan structures of the major lipophosphoglycan surface antigen and released phosphoglycan (Turco et al., 1987; Greis et al., 1992). This study describes a structural...
متن کاملInhibition of human seminal fluid and Leishmania donovani phosphatases by molybdate heteropolyanions.
Inhibition of a tartrate-resistant acid phosphatase (ACP) from Leishmania donovani and the tartrate-sensitive ACP from human seminal fluid (prostatic ACP) was examined using a series of 13 molybdate-containing heteropolyanions. The heteropolyanions were divided into four groups based on the number of molybdenum atoms they contain: Group I, Mo4; Group II, Mo6-8; Group III, Mo12; Group IV, Mo18. ...
