'''CRYSTAL STRUCTURE OF A DISTAL SITE DOUBLE MUTANT OF SPERM WHALE MYOGLOBIN AT 1.6 ANGSTROMS RESOLUTION'''<br />


==Overview==
==CRYSTAL STRUCTURE OF A DISTAL SITE DOUBLE MUTANT OF SPERM WHALE MYOGLOBIN AT 1.6 ANGSTROMS RESOLUTION==
The three-dimensional structure of sperm whale myoglobin, His64(E7)--&gt;Val,Thr67(E10)--&gt;Arg double mutant has been studied by X-ray, crystallography at 1.6 A resolution, and refined to a crystallographic, R-factor of 0.197. The Arg67(E10) side chain is extended in the direction, of the ligand binding site, and its NH1 atom is at a distance of 3.11 A, from the NH1 atom of Arg45(CD3), which is also pointing towards the distal, site. Both are kept in this position by hydrogen bonding and electrostatic, interactions with a solvent sulfate ion, located amongst the two, on the, protein surface. No liganded water molecule is present at the sixth, coordination position of the Fe(III) heme.
