Self-Assembly of Human Serum Albumin: A Simplex Phenomenon
نویسندگان
چکیده
Spontaneous self-assemblies of biomolecules can generate geometrical patterns. Our findings provide an insight into the mechanism of self-assembled ring pattern generation by human serum albumin (HSA). The self-assembly is a process guided by kinetic and thermodynamic parameters. The generated protein ring patterns display a behavior which is geometrically related to a n-simplex model and is explained through thermodynamics and chemical kinetics.

How Do Palladium Complexes Affect on Coil Structure of Human Serum Albumin in the Presence of Carbon Nanotube? A Molecular Dynamics Study
To investigate the interaction and adsorption of drug and carbon nanotube on human serum albumin, three anti-cancer drugs ([Pd(phen)(R-gly)]NO3, R = methyl, propyl and amyl) with different hydrophobic tails and anticancer activities were selected. These drugs have better anti-tumor activity and less side effects than that known cis-platinum drug. Human serum albumin is also ...
متن کاملDirected self-assembly of proteins into discrete radial patterns
Unlike physical patterning of materials at nanometer scale, manipulating soft matter such as biomolecules into patterns is still in its infancy. Self-assembled monolayer (SAM) with surface density gradient has the capability to drive biomolecules in specific directions to create hierarchical and discrete structures. Here, we report on a two-step process of self-assembly of the human serum album...

Human serum albumin is one of the most important blood proteins that has the ability to bind a wide range of compounds and different drugs. Hence, knowing how drugs bind to albumin is crucial to understand their pharmacokinetics and pharmacodynamic properties. The binding of drugs to protein affects the drug's excretion, distribution and interaction in the target tissues. Nicotinamide (NA) is a...

In this article, we address the design of innovative human serum albumin (HSA)-based nanoparticles loaded with silencing RNA and grafted with gadolinium complexes having average sizes ranging from ca. 50 to 150 nm according to the siRNA/HSA composition. The non-covalent siRNA/HSA assembly is formed on isobutyramide-modified mesoporous silica and the self-supported HSA-based nanoparticles are ob...
