Proximal and distal histidine
WebbNeuroglobin (Ngb), the third member of the globin family, was discovered in human and murine brains in 2000. This monomeric globin is structurally similar to myoglobin (Mb) and hemoglobin (Hb) α and β subunits, but it hosts a bis-histidyl six-coordinated heme-Fe atom. Therefore, the heme-based reactivity of Ngb is modulated by the dissociation of the … Webb31 mars 2024 · stabilized through a proximal and distal histidine residue30. In addition, heme chemistry is allosterically regulated by an intramolecular disulfide bridge between Cys38 and Cys839. To determine the role of these structural features, we substituted each of these residues with alanine
