Explaining Urease Specificity Towards Nickel: A Re-Analysis of Its Proposed Mechanism
, 2020 Urease is a binuclear metalloenzyme selective towards nickel, exhibiting a remarkable rate enhancement of the catalytic reaction. The accepted mechanism for urease describes the coordination of urea to both nickel centers in an O,N bridged mode ...

The Urease of Ureaplasma urealyticum [PDF]
Microbiology, 1989 The urease from Ureaplasma urealyticum (serotype 8) has been purified by immuno-affinity column chromatography. Two active nickel-containing forms of the enzyme were demonstrated by non-denaturing electrophoretic analysis and a single active peak of apparent molecular mass 190 kDa was shown by FPLC.
