INTRODUCTION. The urease enzyme of Cryptococcus neoformans is commonly known for its role in cryptococcal virulence during human host infection (Cox et al.2000; Olszewski et al urease positivo. 2004; Shi et al. 2010; Singh et al. 2013).This enzyme catalyses the degradation of urea, resulting in the formation of ammonia and carbamic acid, with the latter undergoing spontaneous hydrolysis to carbonic acid and a .. The Emerging Role of Urease as a General Microbial Virulence Factor - PLOS. Urease activity is the basis of acid acclimation that enables Helicobacter pylori to colonise the acidic environment of the human stomach urease positivo. In response to the acidification of the periplasm of H. pylori, a proton gated urea channel (UreI) imports urea into the bacterial cytosol, where it is hydrolysed by urease [3]..
