Aphidicolin, a specific inhibitor of DNA polymerase alpha, inhibits conversion of lanosterol to C-27 sterols in mouse L cells.
Aphidicolin, a fungal metabolite which is a specific inhibitor of DNA polymerase alpha, inhibited the incorporation of [14C]acetate into desmosterol in mouse L cells by 50% at a concentration of 8.8 microM. It had no effect on acetate metabolism into fatty acids or CO2. The site of inhibition was determined to be distal to the formation of mevalonic acid since aphidicolin also inhibited the inc...
متن کاملStructure-activity relationships for the inhibition of DNA polymerase alpha by aphidicolin derivatives.
Aphidicolin and 17 derivatives that have been structurally modified in the A- and D-rings were assessed for their ability to inhibit DNA polymerase alpha. No derivative surpassed the activity of aphidicolin; derivatives with structural alterations in the A-ring exhibited significantly greater loss of activity relative to derivatives with structural alterations in the D-ring. The conclusions of ...
متن کاملDNA Polymerase III of Escherichia coli
DNA polymerase III, the core of the DNA polymerase III holoenzyme, has been purified Z&000-fold to 97% homogeneity from Escherichiu coli HMS-83. The enzyme contains three subunits: (Y, E, and 0 of 140,000, 25,000, and 10,000 daltons, respectively. The cy subunit has been previously shown to be a component of both DNA polymerase III and the more complex DNA polymerase III holoenzyme (Livingston,...
متن کاملDNA polymerase III holoenzyme of Escherichia coli.
DNA polymerase III holoenzyme has been purified from Escherichia coli HMS-83, using, as an assay, the conversion of coliphage G4 single-stranded DNA to the duplex replicative form. The holoenzyme consists of at least four different subunits: a, /I, y, and 6 of 140,000, 40,000, 52,000, and 32,000 daltons, respectively. The (Y subunit is DNA polymerase III, the dnaE gene product. The holoenzyme h...
