Harnessing microbial-derived metabolites in the urinary tract to prevent infection induced catheter encrustation

Nature Communications
Proteus mirabilis is a predominant cause of catheter associated urinary tract infection (CAUTI), and a key virulence factor is its urease enzyme which can increase urine pH and form urinary stones, causing catheter blockage and facilitating bacteremia ...

Biosynthesis of the Urease Metallocenter [PDF]

Journal of Biological Chemistry, 2013
Metalloenzymes often require elaborate metallocenter assembly systems to create functional active sites. The medically important dinuclear nickel enzyme urease provides an excellent model for studying metallocenter assembly. Nickel is inserted into the urease active site in a GTP-dependent process with the assistance of UreD/UreH, UreE, UreF, and UreG.
