Researchers from Emory University and Georgia Tech have demonstrated the connection between abnormal folding of proteins and the emergence of life. Alzheimer’s disease, and other neurodegenerative conditions involving abnormal folding of proteins, may help explain the emergence of life – and how to create it.
Researchers at Emory University and Georgia Tech demonstrated this connection in two new papers published by Nature Chemistry: “Design of multi-phase dynamic chemical networks” and “Catalytic diversity in self-propagating peptide assemblies.”
“In the first paper we showed that you can create tension between a chemical and physical system to give rise to more complex systems. And in the second paper, we showed that these complex systems can have remarkable and unexpected functions,” said David Lynn, a systems chemist at Emory who led the research. “The work was inspired by our current understanding of Darwinian selection of protein misfolding in neurodegenerative diseases.” [Read more…] about How protein misfolding may kickstart chemical evolution
