Metal-ion dependence of the active-site conformation of the translesion DNA polymerase Dpo4 from Sulfolobus solfataricus.
Acta Crystallogr Sect F Struct Biol Cryst Commun (2010), Volume 66, Page 1013
Abstract:
Crystal structures of a binary Mg2+-form Dpo4-DNA complex with 1,N2-etheno-dG in the template strand as well as of ternary Mg2+-form Dpo4-DNA-dCTP/dGTP complexes with 8-oxoG in the template strand have been determined. Comparison of their conformations and active-site geometries with those of the corresponding Ca2+-form complexes revealed that the DNA and polymerase undergo subtle changes as a result of the catalytically more active Mg2+ occupying both the A and B sites.
