Crystal Structure of HugZ, a Novel Heme Oxygenase from Helicobacter pylori

Abstract excerpt

The crystal structure of a heme oxygenase (HO) HugZ from Helicobacter pylori complexed with heme has been solved and refined at 1.8 Å resolution. HugZ is part of the iron acquisition mechanism of H. pylori, a major pathogen of human gastroenteric diseases. It is required for the adaptive colonization of H. pylori in hosts. Here, we report that HugZ is distinct from all other characterized HOs. It exists as a...
