Rubredoxin

Gene

rub

Organism
Pyrococcus furiosus (strain ATCC 43587 / DSM 3638 / JCM 8422 / Vc1)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein leveli

Functioni

Rubredoxin is a small nonheme, iron protein lacking acid-labile sulfide. Its single Fe, chelated to 4 Cys, functions as an electron acceptor and may also stabilize the conformation of the molecule.

Cofactori

Fe3+Note: Binds 1 Fe3+ ion per subunit.

Temperature dependencei

Extremely thermostable, being unaffected after incubation for 24 hours at 95 degrees Celsius.
