4-HNE-modified ankyrin have been described in diseases such as diabetes, renal failure, G6PD deficient, sickle cell trait and P. falciparum infected erythrocytes with different AB0 blood groups. However, effects at the atomic level of this carbonylation on structure and function of modified protein are not yet fully understood. We present a study based on molecular dynamics simulations of nine 4-HNE modified residues of ZU5-ANK Ankyrin domain with β-spectrin and their binding energy profiles. Results show that 4-HNE induces local conformational changes over all protein systems evaluated, increased mobility in the modification sites and localized structural changes between the positively charged patch of ZU5-ANK domain. Carbonylation with 4-HNE on lysine residues decreased the affinity between ZU5-ANK and the 14-β-Spectrin repeat by reducing electrostatic and Van der Waals interactions. The presented work provides further insight to understand the loss of human erythrocyte deformation capacity under conditions of oxidative stress in different diseases.
