Structure of UreG/UreF/UreH complex reveals how urease accessory proteins facilitate maturation of Helicobacter pylori urease. [PDF]
, 2013 Urease is a metalloenzyme essential for the survival of Helicobacter pylori in acidic gastric environment. Maturation of urease involves carbamylation of Lys219 and insertion of two nickel ions at its active site. This process requires GTP hydrolysis and

Macroscopic Convective Fluid Flows Arising From Binding of Ions and Small Molecules to Proteins
Small, EarlyView.The interaction of ions or small molecules with proteins causes convective flows due to the displacement of water from the hydration shell. As shown, the replacement of the nickel ion removed from urease by EDTA pre‐treatment results in binding‐induced convective fluid flow.

Colloidal Behavior of Carbonate Particles Microbially Precipitated in Microfluidic Droplets
Small, EarlyView.In Microbially Induced Calcium Carbonate Precipitation (MICP), ureolytic bacteria trigger calcium carbonate precipitation via pH‐increasing urea hydrolysis. This enzymatically driven reaction induces the colloidal assembly of bacteria and carbonate particles into fractal networks.

Negative Chemotaxis of Urease‐Functionalized Polymeric Microcapsules
Small, EarlyView.Urease‐functionalized PLGA microcapsules exhibit negative chemotaxis in urea gradients, migrating from high to low substrate concentrations. Increasing gradients enhance chemotaxis until a plateau, while increasing average substrate concentration in a fixed gradient reverses chemotactic behavior.
