Protein

Alkyl hydroperoxide reductase subunit F

Gene

ahpF

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Serves to protect the cell against DNA damage by alkyl hydroperoxides. It can use either NADH or NADPH as electron donor for direct reduction of redox dyes or of alkyl hydroperoxides when combined with the AhpC protein.

Miscellaneous

The active site is a redox-active disulfide bond.
