Produktbeschreibung

Protects DNA from oxidative damage by sequestering intracellular Fe2+ ion and storing it in the form of Fe3+ oxyhydroxide mineral. One hydrogen peroxide oxidizes two Fe2+ ions, which prevents hydroxyl radical production by the Fenton reaction (By similarity). It protects DNA from hydroxyl radical-mediated cleavage. Binds DNA with no apparent sequence specificity without self-aggregation nor promotion of DNA condensation. Is unable to protect DNA from DNase-mediated cleavage. Source: Recombinant protein corresponding to aa1-183 from full length Mycobacterium smegmatis Dps, fused to His-SUMO-Tag at N-terminal, expressed in E. coli.
