Dug1p is a recently identified novel dipeptidase and plays an important role in glutathione (GSH) degradation. To understand the mechanism of its substrate recognition and specificity towards Cys-Gly dipeptides, we characterized the solution properties of Dug1p and studied the thermodynamics of Dug1p–peptide interactions. In addition, we used homology modeling and ligand docking approaches to get...
Pea lectin (PSL) is a dimeric protein in which each subunit comprises two intertwined, post-translationally processed polypeptide chains -a long β-fragment and a short α-fragment. Using guanidine hydrochloride-induced denaturation, we have investigated and characterized the species obtained in the unfolding equilibrium of PSL by steady-state and time-resolved fluorescence, phosphorescence, and selective...
The potential formation of G-quadruplexes in many regions of the genome makes them an attractive target for drug design. A large number of small molecules synthesized in recent years display an ability to selectively target and stabilize G-quadruplexes. To screen for G4 ligands, we modified a G4-FID (G-quadruplex Fluorescent Intercalator Displacement) assay. This test is based on the displacement...
Addition of Vpr C-terminus to various cell types provokes cell apoptosis. This property was recently shown useful to develop inhibitors of cell proliferation. In that context, we investigated the cellular uptake of rhodamine- and fluorescein-labeled Vpr(52–96) peptides to understand the mechanism of Vpr C-terminus entry into cells. Dynamic light scattering data indicated that this peptide spontaneously...
