Efficient conversion of chemical energy into mechanical work by Hsp70 chaperones

Paolo De Los Rios, Salvatore Assenza, Alessandro Barducci, Alberto Stefano Sassi

Hsp70 molecular chaperones are abundant ATP-dependent nanomachines that actively reshape non-native, misfolded proteins and assist a wide variety of essential cellular processes. Here, we combine complementary theoretical approaches to elucidate the struct ...

Chaperones convert the energy from ATP into the nonequilibrium stabilization of native proteins

Paolo De Los Rios, Bruno Claude Daniel Fauvet, Alessandro Barducci, Alberto Stefano Sassi, Pierre Goloubinoff

During and after protein translation, molecular chaperones require ATP hydrolysis to favor the native folding of their substrates and, under stress, to avoid aggregation and revert misfolding. Why do some chaperones need ATP, and what are the consequences ...

Non equilibrium thermodynamics of protein organization

Alberto Stefano Sassi

Three quarters of the thesis will be devoted to the discussion of non equilibrium systems. We show how certain biological systems cannot be described by standard thermodynamics. The reason is that the energy consumption due to the hydrolysis of ATP imposes ...
