Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 5-Iodo-2-furaldehyde, is researched, Molecular C5H3IO2, CAS is 2689-65-8, about Improving the Solubility of Artificial Ligands of Streptavidin to Enable More Practical Reversible Switching of Protein Localization in Cells.Name: 5-Iodo-2-furaldehyde.
Chem. inducers that can control target-protein localization in living cells are powerful tools to investigate dynamic biol. systems. We recently reported the retention using selective hook or “”RUSH”” system for reversible localization change of proteins of interest by addition/washout of small-mol. artificial ligands of streptavidin (ALiS). However, the utility of previously developed ALiS was restricted by limited solubility in water. Here, we overcame this problem by X-ray crystal structure-guided design of a more soluble ALiS derivative (ALiS-3), which retains sufficient streptavidin-binding affinity for use in the RUSH system. The ALiS-3-streptavidin interaction was characterized in detail. ALiS-3 is a convenient and effective tool for dynamic control of a-mannosidase II localization between ER and Golgi in living cells.
