CC   -!- FUNCTION: Facilitates the functional incorporation of the urease nickel
CC       metallocenter. This process requires GTP hydrolysis, probably
CC       effectuated by UreG. {ECO:0000255|HAMAP-Rule:MF_01389}.
CC   -!- SUBUNIT: Homodimer. UreD, UreF and UreG form a complex that acts as a
CC       GTP-hydrolysis-dependent molecular chaperone, activating the urease
CC       apoprotein by helping to assemble the nickel containing metallocenter
CC       of UreC. The UreE protein probably delivers the nickel.
CC       {ECO:0000255|HAMAP-Rule:MF_01389}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01389}.
CC   -!- SIMILARITY: Belongs to the SIMIBI class G3E GTPase family. UreG
CC       subfamily. {ECO:0000255|HAMAP-Rule:MF_01389}.
