New biologically derived metal-organic framework mimics DNA
A team of chemical engineers at EPFL Valais Wallis have synthesized a new biologically-derived MOF that can be used as a “nanoreactor” – a place where tiny, otherwise-inaccessible reactions can take place. Led by Kyriakos Stylianou, scientists from the labs of Berend Smit , deputy director of MARVEL, and Lyndon Emsley constructed and analyzed the new MOF with adenine molecules – one of the four nucleobases that make up DNA and RNA.
The idea behind this was to mimic the functions of DNA, one of which include hydrogen-bonding interactions between adenine and another nucleobase, thymine. This is a critical step in the formation of the DNA double helix, but it also contributes to the overall folding of both DNA and RNA inside the cell.
