Sequence similarity between the erythrocyte binding domain of the Plasmodium vivax Duffy binding protein and the V3 loop of HIV-1 strain MN reveals a functional heparin binding motif involved in binding to the Duffy antigen receptor for chemokines [PDF]

open access: yes, 2011
Background The HIV surface glycoprotein gp120 (SU, gp120) and the Plasmodium vivax Duffy binding protein (PvDBP) bind to chemokine receptors during infection and have a site of amino acid sequence similarity in their binding domains that often includes a

New Insight on In Vitro Biological Activities of Sulfated Polysaccharides from Ulvophyte Green Algae

open access: yesMolecules, 2023
Green algae are natural bioresources that have excellent bioactive potential, partly due to sulfated polysaccharides (SPs) which are still rarely explored for their biological activities.

Food Xanthan Polysaccharide Sulfation Process with Sulfamic Acid [PDF]

open access: yesFoods, 2021
Xanthan is an important polysaccharide with many beneficial properties. Sulfated xanthan derivatives have anticoagulant and antithrombotic activity. This work proposes a new method for the synthesis of xanthan sulfates using sulfamic acid. Various N-substituted ureas have been investigated as process activators.

Heparin binding preference and structures in the fibroblast growth factor family parallel their evolutionary diversification [PDF]

open access: yes, 2016
The interaction of a large number of extracellular proteins with heparan sulfate (HS) regulates their transport and effector functions, but the degree of molecular specificity underlying protein–polysaccharide binding is still debated.
