MeSH headings : Animals; Crystallization; Crystallography, X-Ray; Heme Oxygenase (Decyclizing) / chemistry; Heme Oxygenase (Decyclizing) / metabolism; Hemoglobins / chemistry; Hemoglobins / metabolism; Histidine / chemistry; Histidine / metabolism; Iodobenzenes / chemistry; Iodobenzenes / metabolism; Peroxidases / chemistry; Peroxidases / metabolism; Polychaeta / enzymology; Protein Binding; Protein Conformation; Solvents
TL;DR: It is reported that the distal histidine, His55, exhibits conformational flexibility in the deoxy form and is consequently observed in two solvent-exposed conformations more than 9.5 A away from the heme, analogous to the open conformation of sperm whale myoglobin. (via Semantic Scholar)
