Polymerase I

Nitrofurantoin (1-([(5-nitrofuran-2-yl)methylene]amino)imidazolidine-2,4-dione), a widely used drug and also a well-known bacterial mutagen, inhibits DNA synthesis in mitochondria from 48 h etiolated seedlings of Vigna sinensis (Linn.) Savi (snake bean). The effect appears at the level of the uptake of radioactive deoxynucleoside triphosphates by the plant mitochondria. Nitrofurantoin does not inhibit DNA synthesis in vitro by homogeneous Escherichia coli DNA polymerase I and DNA polymerase from avian-myeloblastosis virus. No specific nitroreductase activity could be detected in mitochondria.

High resolution crystal structures of DNA polymerase intermediates are needed to study the mechanism of DNA synthesis in cells. Here we report five crystal structures of DNA polymerase I that capture new conformations for the polymerase translocation and nucleotide pre-insertion steps in the DNA synthesis pathway. We suggest that these new structures, along with previously solved structures, highlight the dynamic nature of the finger subdomain in the enzyme active site.
