Purification and characterization of Helicobacter mustelae urease.

B E Dunn¹, C C Sung, N S Taylor, J G Fox.

Abstract

Helicobacter mustelae is a urease-rich bacterium associated with gastritis in ferrets. The ureases of H. mustelae and Helicobacter pylori, a bacterium implicated in human gastritis, share many characteristics. Helicobacter sp. ureases appear to be unique among bacterial enzymes in exhibiting submillimolar Km values and in being composed of two subunits.
