Proximal influences in two-on-two globins: Effect of the Ala69Ser replacement on Synechocystis sp. PCC 6803 hemoglobin

The cyanobacterium Synechocystis sp. PCC 6803 (S6803) expresses a two-on-two globin in which His46 (distal side) and His70 (proximal) function as heme iron axial ligands. His46 can be displaced by O(2), CO, and CN(−), among others, whereas His70 is not labile under native conditions. The residue pre...
