We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

'''X-RAY CRYSTAL STRUCTURE OF A RECOMBINANT HUMAN MYOGLOBIN MUTANT AT 2.8 ANGSTROMS RESOLUTION'''
+
-

-

-
==Overview==
+
-
We have grown crystals in trigonal space group P3(2)21 of a mutant human myoglobin, aquomet form, in which lysine at position 45 has been replaced by arginine and cysteine at position 110 has been replaced by alanine. Suitable crystals of native recombinant human myoglobin have not been obtained. We have used the molecular replacement method to determine the X-ray crystal structure of the mutant at 2.8 A resolution. At the present stage of refinement, the crystallographic R-value for the model, with tightly restrained stereochemistry, is 0.158 for 5.0 to 2.8 A data. As expected, the overall structure is quite similar to the sperm whale myoglobin structure. Arginine 45 adopts a well-ordered conformation similar to that found in aquomet sperm whale myoglobin.
