ureEFGD
Providencia rettgeri. UreEFGD protein coding region.This part enable the expression of the four accessory subunits of urease enzymes.
Usage and Biology
ureEFGD are urease (accessory) proteins, responsible for the activation of the ureABC proenzyme.bacterial urease genes were widely reported in a way of urease gene cluster, which was consisted of structural genes and accessory genes. Structural subunits of urease were encoded by structural genes (ureABC), and accessory subunits of urease were encoded by accessory genes (ureEFGD).
This part has three structural genes (ureA, ureB and ureC) and four accessory genes (ureE, ureF, ureG and ureD). It was also indicated that in addition to the above structural subunits of urease, accessory proteins are required in bacteria for the expression of active ureases. The genes encoding these proteins have been found in various arrangements adjacent to the structural genes. The protein products of the accessory genes (ureDEFG) are involved in the incorporation of nickel ions into the apoenzyme of urease.
We constructed a related plasmid and expressed it.

Characterization
1. Agarose Gel Electrophoresis:
As an important auxiliary structure of urease, we also obtained it from the genome of Providencia rettgeri strain JNB815 and recombined it into the pETlac plasmid using the same method..
