ATOMIC RESOLUTION STRUCTURE OF D92E MUTANT OF ALCALIGENES XYLOSOXIDANS NITRITE REDUCTASE
OverviewOverview
We provide the first atomic resolution (<1.20 A) structure of a copper, protein, nitrite reductase, and of a mutant of the catalytically important, Asp92 residue (D92E). The atomic resolution where carbon-carbon bonds of, the peptide become clearly resolved, remains a key goal of structural, analysis. Despite much effort and technological progress, still very few, structures are known at such resolution. For example, in the Protein Data, Bank (PDB) there are some 200 structures of copper proteins but the, highest resolution structure is that of amicyanin, a small (12 kDa), protein, which has been resolved to 1.30 A. Here, we present the, structures of wild-type copper nitrite reductase (wtNiR) from Alcaligenes, xylosoxidans (36.5 kDa monomer), the "half-apo" recombinant native protein, and the D92E mutant at 1.04, 1.15 and 1.12A resolutions, respectively., These structures provide the basis from which to build a detailed, mechanism of this important enzyme.
