ABSTRACT
|
|
|
| |
|
A reaction cycle is proposed for the mechanism of copper-zinc superoxide
dismutase (CuZnSOD) that involves inner sphere electron transfer from superoxide
to Cu(II) in one portion of the cycle and outer sphere electron transfer from
Cu(I) to superoxide in the other portion of the cycle. This mechanism is based
on three yeast CuZnSOD structures determined by X-ray crystallography together
with many other observations. The new structures reported here are (1) wild type
under 15 atm of oxygen pressure, (2) wild type in the presence of azide, and (3)
the His48Cys mutant. Final R-values for the three structures are respectively
20.0%, 17.3%, and 20.9%. Comparison of these three new structures to the
wild-type yeast Cu(I)ZnSOD model, which has a broken imidazolate bridge, reveals
the following: (i) The protein backbones (the "SOD rack") remain essentially
unchanged. (ii) A pressure of 15 atm of oxygen causes a displacement of the
copper ion 0.37 A from its Cu(I) position in the trigonal plane formed by His46,
His48, and His120. The displacement is perpendicular to this plane and toward
the NE2 atom of His63 and is accompanied by elongated copper electron density in
the direction of the displacement suggestive of two copper positions in the
crystal. The copper geometry remains three coordinate, but the His48-Cu bond
distance increases by 0.18 A. (iii) Azide binding also causes a displacement of
the copper toward His63 such that it moves 1.28 A from the wild-type Cu(I)
position, but unlike the effect of 15 atm of oxygen, there is no two-state
character. The geometry becomes five-coordinate square pyramidal, and the His63
imidazolate bridge re-forms. The His48-Cu distance increases by 0.70 A,
suggesting that His48 becomes an axial ligand. (iv) The His63 imidazole ring
tilts upon 15 atm of oxygen treatment and azide binding. Its NE2 atom moves
toward the trigonal plane by 0.28 and 0.66 A, respectively, in these structures.
(v) The replacement of His48 by Cys, which does not bind copper, results in a
five-coordinate square pyramidal, bridge-intact copper geometry with a novel
chloride ligand. Combining results from these and other CuZnSOD crystal
structures, we offer the outlines of a structure-based cyclic mechanism.

Citation data come partly from CiteXplore and partly
from an automated harvesting procedure. Note that this is likely to be
only a partial list as not all journals are covered by
either method. However, we are continually building up the citation data
so more and more references will be included with time.
