Structural characterization of the urease accessory protein UreF from Klebsiella pneumoniae.

ABSTRACT: Klebsiella pneumoniae is an opportunistic pathogen that mostly affects those with weakened immune systems. Urease is a vital enzyme that can hydrolyze urea to ammonia and carbon dioxide as a source of nitrogen for growth. Urease is also a K. pneumoniae virulence factor that enables survival of the bacterium under nutrient-limiting conditions. UreF, an important nickel-binding urease accessory protein, is involved in the insertion of Ni²⁺ into the active site of urease. Here, the crystal structure of UreF from K. pneumoniae (KpUreF) is reported. Functional data show that KpUreF forms a stable dimer in solution. These results may provide a starting point for the design of urease inhibitors.
