CRYSTAL STRUCTURE OF PEROXYNITRITE-MODIFIED BOVINE CU,ZN SUPEROXIDE DISMUTASE


Overview

The crystal structure of bovine Cu,Zn superoxide dismutase modified with peroxynitrite (ONOO-) was determined by X-ray diffraction, utilizing the existing three-dimensional model of the native structure deposited in the Brookhaven Protein Data Bank (J. A. Tainer et al., J. Mol. Biol. 160, 181-217, 1982). The native structure and the modified derivative were refined to R factors of 19.0 and 18.7% respectively using diffraction data from 6.0 to 2.5 A. The major result after reaction with peroxynitrite was the appearance of electron density 1.45 A from a single epsilon carbon of Tyr-108, the only tyrosine residue in the sequence. Tyr-108 is a solvent-exposed residue 18 A from the copper atom in the active site. The electron density was consistent with nitration of Tyr-108 at one of the epsilon carbons to form 3-nitrotyrosine. We propose that the nitration occurs in solution by transfer of a nitronium-like species from the active site on one superoxide dismutase dimer to the Tyr-108 of a second dimer.
