Steric hindrance effects in thin reaction zones: applications to BIAcore
Many biological and industrial processes have reactions which occur in thin zones of densely packed receptors. Understanding the rate of such reactions is important, and the BIAcore surface plasmon resonance biosensor for measuring rate constants has such a geometry. However, interpreting biosensor data correctly is difficult since large ligand molecules can block multiple receptor sites, thus ...
متن کاملSteric hindrance effects on surface reactions: applications to BIAcore.
Because surface-volume reactions occur in many biological and industrial processes, understanding the rate of such reactions is important. The BIAcore surface plasmon resonance (SPR) biosensor for measuring rate constants has such a geometry. Though several models of the BIAcore have been presented, few take into account that large ligand molecules can block multiple receptor sites, thus skewin...
متن کاملConstruction of polymer-protein bioconjugates with varying chain topologies: polymer molecular weight and steric hindrance effects.
We report on the fabrication of well-defined polymer-protein bioconjugates with varying chain architectures, including star polymers, star block copolymers, and heteroarm star copolymers through the specific noncovalent interaction between avidin and biotinylated synthetic polymer precursors. Homopolymer and diblock precursors site-specifically labeled with a single biotin moiety at the chain t...
متن کاملUnusual oxidation of glutathione existing the steric hindrance
Research on the electro-oxidation of glutathione (GSH) may give insight into its real oxidation mechanism on biomembranes. In the present work, the unusual oxidation process of GSH on an Au electrode was probed by cyclic voltammetry (CV) technique. Voltammetric studies showed that –SH in GSH was the unique target of electro-oxidation by excluding the other potential oxidation sites (amido group...
متن کاملEvidence that regulatory protein MarA of Escherichia coli represses rob by steric hindrance.
The MarA protein of Escherichia coli can both activate and repress the initiation of transcription, depending on the position and orientation of its degenerate 20-bp binding site ("marbox") at the promoter. For all three known repressed genes, the marbox overlaps the promoter. It has been reported that MarA represses the rob promoter via an RNA polymerase (RNAP)-DNA-MarA ternary complex. Under ...
