'''ATOMIC RESOLUTION STRUCTURE OF D92E MUTANT OF ALCALIGENES XYLOSOXIDANS NITRITE REDUCTASE'''
===ATOMIC RESOLUTION STRUCTURE OF D92E MUTANT OF ALCALIGENES XYLOSOXIDANS NITRITE REDUCTASE===




==Overview==
<!--
We provide the first atomic resolution (&lt;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.
The line below this paragraph, {{ABSTRACT_PUBMED_12691751}}, adds the Publication Abstract to the page
(as it appears on PubMed at http://www.pubmed.gov), where 12691751 is the PubMed ID number.
