ATOMIC RESOLUTION CRYSTAL STRUCTURE ANALYSIS OF NATIVE DEOXY AND CO MYOGLOBIN FROM SPERM WHALE AT ROOM TEMPERATUREATOMIC RESOLUTION CRYSTAL STRUCTURE ANALYSIS OF NATIVE DEOXY AND CO MYOGLOBIN FROM SPERM WHALE AT ROOM TEMPERATURE
Structural highlights
Function[MYG_PHYMC] Serves as a reserve supply of oxygen and facilitates the movement of oxygen within muscles. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe crystal structures of myoglobin in the deoxy- and carbon monoxide-ligated states at a resolution of 1.15 angstroms show that carbon monoxide binding at ambient temperatures requires concerted motions of the heme, the iron, and helices E and F for relief of steric inhibition. These steps constitute the main mechanism by which heme proteins lower the affinity of the heme group for the toxic ligand carbon monoxide. A steric mechanism for inhibition of CO binding to heme proteins.,Kachalova GS, Popov AN, Bartunik HD Science. 1999 Apr 16;284(5413):473-6. PMID:10205052[1] From MEDLINE®/PubMed®, a database of the U.S. National Library of Medicine. References |
