NH2COOH (1) Although it has commonly been assumed that the properties of
jack bean urease hold for ureases from other sources, there is good evidence
that ureases from different sources exhibit different properties (Reithel, 1971; ...
Acute acid resistance is due to the urease/Urel system, which responds in
seconds to an acid stress. Intermediate acid resistance is due to an increase in
urease activity by incorporation of Ni2+ into apoenzyme, independent of de novo
protein ...

The urease theory attempts to explain how the flow of nutrients from photobiont to
fungus may be regulated (Vicente et al., 1978) (Fig. 47). Urease is a common
enzyme in lichens and has been studied extensively with regard to the surface ...
