Nanocages dramatically facilitate structure formation of biomolecules
Nano-size space help faster folding of molecules and stabilize the structure, which regulates enzyme reactions
Macromolecules regularly fold and unfold themselves inside cells. Their diverse three-dimensional structures help determine their functions. Understanding molecule folding can shed light on complex physical processes that may influence diseases, cancers and allergies.
A team led by Hiroshi Sugiyama and Masayuki Endo of iCeMS collaborating with the team from Kent State University designed structures and experimental system that successfully manipulates G-quadruplexes (groups of guanine nucleic acids, the ‘G’s in the DNA sequence) inside nanocages, which are also made of DNA. The team measured how different-sized spaces affect the thermodynamic stability and unfolding and folding kinetics of these molecules.
