The Maturation Pathway of Nickel Urease

open access: yesInorganics, 2019
Maturation of urease involves post-translational insertion of nickel ions to form an active site with a carbamylated lysine ligand and is assisted by urease accessory proteins UreD, UreE, UreF and UreG.

A Novel Immobilization Method of Urease in Silk Fibroin Scaffolds by Annealing at Constant Temperature and Humidity

open access: yesMacromolecular Materials and Engineering, 2023
Temperature and humidity (TH) post‐treatment is a relatively mild way to change the silk fibroin (SF) secondary structure. Here, urease is immobilized in SF scaffold (SFS) by TH post‐treatment, and the effects of annealing on the immobilized urease ...
