Reaction of the XPA zinc finger with S-nitrosoglutathione.
Smirnova J, Zhukova L, Witkiewicz-Kucharczyk A, Kopera E, Oledzki J, Wysłouch-Cieszyńska A, Palumaa P, Hartwig A, Bal W. Smirnova J, et al. Among authors: hartwig a. Chem Res Toxicol. 2008 Feb;21(2):386-92. doi: 10.1021/tx700297f. Epub 2008 Jan 3. Chem Res Toxicol. 2008. PMID: 18171019
Mechanism of nickel assault on the zinc finger of DNA repair protein XPA.
Bal W, Schwerdtle T, Hartwig A. Bal W, et al. Among authors: hartwig a. Chem Res Toxicol. 2003 Feb;16(2):242-8. doi: 10.1021/tx025639q. Chem Res Toxicol. 2003. PMID: 12588196
Xeroderma pigmentosum group A complementing protein (XPA) is a member of the protein complex of the nucleotide excision repair (NER) pathway of DNA repair, participating in the assembly of the incision complex. ...As demonstrated previously, the activity of XPA is c …

Co(II) and Cd(II) substitute for Zn(II) in the zinc finger derived from the DNA repair protein XPA, demonstrating a variety of potential mechanisms of toxicity.
Kopera E, Schwerdtle T, Hartwig A, Bal W. Kopera E, et al. Among authors: hartwig a. Chem Res Toxicol. 2004 Nov;17(11):1452-8. doi: 10.1021/tx049842s. Chem Res Toxicol. 2004. PMID: 15540943
To study the possible molecular mechanisms of XPA inhibition, we previously investigated Zn(II) and Ni(II) interactions with the synthetic 37 amino acid peptide (XPAzf), AcDYVICEECGKEFMDSYLMNHFDLPTCDNCRDADDKHKam, representing the XPA zinc finger sequence (Bal, W., Schwerdtle, T., …

Monomethylarsonous acid destroys a tetrathiolate zinc finger much more efficiently than inorganic arsenite: mechanistic considerations and consequences for DNA repair inhibition.
Piatek K, Schwerdtle T, Hartwig A, Bal W. Piatek K, et al. Among authors: hartwig a. Chem Res Toxicol. 2008 Mar;21(3):600-6. doi: 10.1021/tx7003135. Epub 2008 Jan 26. Chem Res Toxicol. 2008. PMID: 18220366
Previously, we demonstrated that methylated As (III) compounds are more efficient than arsenite in releasing zinc from ZnXPAzf, the zinc finger of XPA, a crucial member of the NER complex [Schwerdtle, T., Walter, I., and Hartwig, A. (2003) Arsenite and its bi …
