Histidine–Lysine Axial Ligand Switching in a Hemoglobin: A Role for Heme Propionates

The hemoglobin of Synechococcus sp. PCC 7002, GlbN, is a monomeric group I truncated protein (TrHb1) that coordinates the heme iron with two histidine ligands at neutral pH. One of these is the distal histidine (His46), a residue displaceable by dioxygen and other small molecules. Here, we show with...
