Chemists brought mixed folded proteins to life

(ITMO University) Scientists from ITMO University in Saint Petersburg and Hebrew University in Jerusalem have found a way to recover a protein structure after its chemical denaturation. The method is based on electrostatic interaction between folded, or denatured, proteins and alumina, which unwrap them. Importantly, this technique works for multiprotein systems -- nobody has been able to recover mixtures of enzymes before. This can help simplify and cheapen the production of drug proteins for A...
