Ureases are moonlighting proteins displaying non-catalytic properties, including platelet activation, antifungal and entomotoxic effects. The structure-activity mapping of these properties is poorly developed. Proteus mirabilis urease (PMU) consists three subunits, PmUre?, PmUre? PmUre?, in an (???)3 organization. In order to study the relationships PMU we obtained recombinant subunits this eva...
