Fig. 4From: A recurrent single-amino acid deletion (p.Glu500del) in the head domain of ß-cardiac myosin in two unrelated boys presenting with polyhydramnios, congenital axial stiffness and skeletal myopathyIntramolecular interactions involving p.Glu500, as predicted by AlphaFold. Close-up on the alpha-helix of the relay loop. p.Glu500 (colored in pink) is situated close to one end of the helix and is expected to engage in electrostatic interactions (dashed blue lines) with Lysine503 and Lysine762. Deletion of p.Glu500 may abolish these interactions and dislocate the positively charged amino group of Lysine503Back to article page
