Albumin-induced circular dichroism in Congo red: applications for studies of amyloid-like fibril aggregates and binding sites
(Elsevier B. V., 2015-11-05)
Congo red (CR), one of the most commonly used dyes for the identification of amyloid fibril aggregates, is also a ligand of native bovine serum albumin (BSA). Induced circular dichroism (ICD) is a phenomenon observed when ...
β-Lactoglobulin heat-induced aggregates as carriers of polyunsaturated fatty acids
(Elsevier, 2014-02)
The aim of this work was to obtain heat-induced β-lactoglobulin (BLG) aggregates in order to test them as carriers of a model polyunsaturated fatty acid (PUFA), linoleic acid (LA). BLG aggregates were obtained at 85 °C by ...
Equilibrium mono- and multicomponent adsorption models: From homogeneous ideal to heterogeneous non-ideal binding
(Elsevier Science, 2020-06)
Aqueous sorption processes play an important role in, for example, pollutant binding to natural nanoparticles, colloid stability, separation and enrichment of components and remediation processes. In this article, which ...
Signaling Events During Cyclic Guanosine Monophosphate-Regulated Pigment Aggregation in Freshwater Shrimp Chromatophores
(MARINE BIOLOGICAL LABORATORYWOODS HOLE, 2012)
Crustacean color change results partly from granule aggregation induced by red pigment concentrating hormone (RPCH). In shrimp chromatophores, both the cyclic GMP (3', 5'-guanosine monophosphate) and Ca2+ cascades mediate ...
Uncoupling the MgATP-induced inhibition and aggregation of Escherichia coli phosphofructokinase-2 by C-terminal mutations
(ELSEVIER, 2008-06-11)
Binding of MgATP to an allosteric site of Escherichia coli phosphofructokinase-2 (Pfk-2) provoked inhibition and a dimer-tetramer (D-T) conversion of the enzyme. Successive deletions of up to 10 residues and point mutations ...
