The role of the heme distal ligand in the post-translational modification of Synechocystis hemoglobin

Synechocystis sp. PCC 6803 hemoglobin is a cyanobacterial Group I truncated hemoglobin. In the absence of an exogenous ligand, its single heme group is coordinated by His46 (E10, distal) and His70 (F8, proximal). The protein can undergo a post-translational modification by which His117 (H16, in the...
