WebbThere is a “proximal” histidine ligand (His175) which is hydrogen bonded to Asp and Trp residues on the proximal side of the heme. On the distal side, there is a “distal” histidine residue together with distal Arg and Trp residues. In most other peroxidases, such as HRP, the proximal and distal Trp residues are replaced with Phe, Fig. 2. Webb27 sep. 2024 · APX. In all three proteins, the proximal (also called axial) histidine ligand is part of a hydrogen bonding network and interacts with the carboxylate of an Asp residue … WebbExplain whatthe distal and proximal histidines of myoglobin and hemoglobin are and their functions in oxygen binding.
