DNA alkylation can cause mutations, epigenetic changes, and even cell death. All living organisms have evolved enzymatic and non-enzymatic strategies for repairing such alkylation damage. AlkB, one of the Escherichia coli adaptive response proteins,

The AlkB enzyme is an Fe(II)- and α-ketoglutarate-dependent dioxygenase that repairs DNA alkyl lesions by a direct reversal of damage mechanism as part of the adaptive response in E. coli. The reported substrate scope of AlkB includes simple DNA alk

Oxidation in therapeutic monoclonal antibody is a common occurrence and it may affect potency. Thus controlling and monitoring the amount of oxidized variant in the drug product sample is important since it may impact the purity. Here, we present the

When exposed to known DNA-damaging alkylating agents, Escherichia coli cells increase production of four DNA repair enzymes: Ada, AlkA, AlkB, and AidB. The role of three enzymes (Ada, AlkA, and AlkB) in repairing DNA lesions has been well characteriz

The DNA and RNA repair protein AlkB removes alkyl groups from nucleic acids by a unique iron- and α-ketoglutarate-dependent oxidation strategy. When alkylated adenines are used as AlkB targets, earlier work suggests that the initial target of oxidat

Exposure of Escherichia coli cells to small doses of DNA-methylating agents initiates a response that mitigates the mutagenic and cytotoxic effects of DNA methylation.1−3 This process, known as the adaptive response, involves the upregulation of fo

CytC3, a member of the recently discovered class of nonheme Fe(II) and alpha-ketoglutarate (alphaKG)-dependent halogenases, catalyzes the double chlorination of L-2-aminobutyric acid (Aba) to produce a known Streptomyces antibiotic, gamma,gamma-dichl

Oxidative stress converts lipids into DNA-damaging agents. The genomic lesions formed include 1,N(6)-ethenoadenine (epsilonA) and 3,N(4)-ethenocytosine (epsilonC), in which two carbons of the lipid alkyl chain form an exocyclic adduct with a DNA base
