Replacement of the Distal Histidine Reveals a Non-Canonical Heme Binding Site in a 2-on-2 Hemoglobin

Heme ligation in hemoglobin is typically assumed by the “proximal” histidine. Hydrophobic contacts, ionic interactions, and the ligation bond secure the heme between two α- helices denoted E and F. Across the hemoglobin superfamily, several proteins also use a “distal” histidine, making the native s...
