CRYSTAL STRUCTURE OF H129V MUTANT OF ALCALIGENES XYLOSOXIDANS NITRITE REDUCTASE

OverviewOverview

Copper nitrite reductases contain both an electron-transfer type 1 Cu site, and a catalytic type 2 Cu site. We have mutated one of the type 2 copper, ligating histidines to observe the effect on catalytic turnover. This, mutation has created a unique site where Cu is ligated by 2 His Nepsilon2, atoms alone.
