From: Interactions of HLA-DR and Topoisomerase I Epitope Modulated Genetic Risk for Systemic Sclerosis

Hydrogen bond (HB) interactions of HLA-DR/Top1 complexes. HBs between HLA-DR (vertical axis) and Top1 (horizontal axis) residues are presented by grid map. Atom types are specified by tleap AMBER conversion. HB strength is defined by label and color in the grid cells, while salt bridge (SB) interaction is framed by a black border.
