The N-Terminal Domain of Human DNA Helicase Rtel1 Contains a Redox Active Iron-Sulfur Cluster

<table>Alignment of the N-terminal domain of some human DNA helicases. Sequence alignment of yeast DNA helicase Rad3 and human DNA helicase XPD, Rtel1, FancJ, and Chl1 was generated by cobalt (NCBI). Four conserved cysteine residues proposed for hosting an iron-sulfur cluster in these DNA helicases are highlighted in yellow.</table>
