Enzymes whose catalytic activity depends on multimeric assembly are targets for inhibitors that perturb the interactions between the protein subunits such as the HIV-1 Integrase (IN). Sucrose has been recently crystallized in complex with IN revealing an allosteric binding pocket at the monomer-monomer interface.

Abstract
Enzymes whose catalytic activity depends on multimeric assembly are targets for inhibitors that perturb the interactions between the protein subunits such as the HIV-1 Integrase (IN). Sucrose has been recently crystallized in complex with IN revealing an allosteric binding pocket at the monomer-monomer interface. Herein, molecular dynamics were applied to theoretically test the effect of this small ligand on IN. As a result, such a compound increases the mutual free energy of binding between the two interacting monomers. Biological experiments confirmed the computational forecast.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
