AlkB Protein, E.coli (Myc, His-SUMO)

AlkB Protein, E.coli (Myc, His-SUMO) is a protein found in E. coli, plays a major role in oxidative dealkylation processes.

Iron-dependent dioxygenases of the AlkB protein family found in most organisms throughout the tree of life play a major role in oxidative dealkylation processes. In higher eukaryotes including yeast, plants and mammals, members of the AlkB family play pivotal roles. In humans, this family draws particular interest because of its involvement in DNA repair and progression of cancer, as they are frequently overexpressed in tumors and counteract the effects of alkylating drugs such as temozolamide used in chemotherapy. The alkylation-sensitive phenotype of E. coli alkB mutants marks the alkB pathway as an extremely effective defense mechanism against the cytotoxic effects of the SN2, but not the SN1, alkylating agents^[1][2].

The enzyme activity of this recombinant protein is testing in progress, we cannot offer a guarantee yet.
