"WebSperm whale myoglobin is a 17.7 kDa globular protein consisting of eight helical segments (named A-H). For all studies, we will use the apo-form to avoid resonance energy transfer from the excited tryptophan residue to the prosthetic heme group. At pH=6, apomyoglobin is in the native state, but at pH=4, it becomes a molten globule structure. " - Sperm whale myoglobin
