RUBREDOXIN OXYGEN:OXIDOREDUCTASE (ROO) FROM ANAEROBE DESULFOVIBRIO GIGAS
Overview
Desulfovibrio gigas is a strict anaerobe that contains a, well-characterized metabolic pathway that enables it to survive transient, contacts with oxygen. The terminal enzyme in this pathway, rubredoxin:oxygen oxidoreductase (ROO) reduces oxygen to water in a direct, and safe way. The 2.5 A resolution crystal structure of ROO shows that, each monomer of this homodimeric enzyme consists of a novel combination of, two domains, a flavodoxin-like domain and a Zn-beta-lactamase-like domain, that contains a di-iron center for dioxygen reduction. This is the first, structure of a member of a superfamily of enzymes widespread in strict and, facultative anaerobes, indicating its broad physiological significance.
