Inhibition of RNA-directed DNA polymerase by aurintricarboxylic acid.

Commercial-grade aurintricarboxylic acid (ATA) inhibits poly(A), poly(C) and viral RNA-directed DNA synthesis by detergent-disrupted virions of Moloney murine leukemia virus. Paper chromatography of crude ATA yields two active components, which appear to behave identically, and at least two inactive components. The concentration of ATA needed to inhibit polymerase activity is proportional to th...

Inhibition of enterovirus 71 replication and the viral 3D polymerase by aurintricarboxylic acid.

OBJECTIVES Enterovirus 71 (EV71) causes serious diseases in humans. The aim of this study was to examine the effects of aurintricarboxylic acid (ATA) on EV71 replication and to explore the underlying mechanism. METHODS To measure the activity of ATA in inhibiting the cytopathic effect (CPE) of EV71, a cell-based neutralization (inhibition of virus-induced CPE) assay was performed. The effect ...

Primer recognition by avian myeloblastosis virus RNA-directed DNA polymerase.

Tryptophanyl-tRNA was specifically labeled at the 3' end with [3H]tryptophan and cleaved in half with RNase under denaturing conditions, and the 3' half was shown to hybridize exclusively at the 5' end of avian myeloblastosis virus RNA. The RNA-dependent DNA polymerase of avian myeloblastosis virus is capable of efficiently binding the 3' half of the primer molecule.

Inhibition by aurintricarboxylic acid and polyethylene sulfonate of RNA transcription of vesicular stomatitis virus.

The in vitro activity of the ribonucleoprotein-dependent RNA transcriptase of vesicular stomatitis virions was found to be completely inhibited by low concentrations of aurintricarboxylic acid (ATA) and polyethylene sulfonic acid (PES) when these inhibitors were added before the start of the RNA polymerase reaction. However, if RNA synthesis was allowed to occur before ATA or PES was added, RNA...

Directed evolution of novel polymerase activities: mutation of a DNA polymerase into an efficient RNA polymerase.

The creation of novel enzymatic function is of great interest, but remains a challenge because of the large sequence space of proteins. We have developed an activity-based selection method to evolve DNA polymerases with RNA polymerase activity. The Stoffel fragment (SF) of Thermus aquaticus DNA polymerase I is displayed on a filamentous phage by fusing it to a pIII coat protein, and the substra...
