Bacterial hemerythrin domain-containing oxygen and redox sensors: Versatile roles for oxygen and redox signaling

open access: yesFrontiers in Molecular Biosciences, 2022
Hemerythrin is an oxygen-binding protein originally found in certain marine invertebrates. Oxygen reversibly binds at its non-heme diiron center, which consists of two oxo-bridged iron atoms bound to a characteristic conserved set of five His residues ...

Redox regulation of the NPR1-TGA1 system of Arabidopsis thaliana by nitric oxide [PDF]

open access: yes, 2010
The role of reactive oxygen and nitrogen species in local and systemic defense reactions is well documented. NPR1 and TGA1 are key redox-controlled regulators of systemic acquired resistance in plants. NPR1 monomers interact with the reduced form of TGA1,
