Abstract: | A method is described for the rapid purification of RNA polymerase holoenzyme from small amounts of Escherichia coli cells. Chromatography of a crude extract on a single-stranded DNA agarose column followed by gel filtration chromatography gave 95% pure holoenzyme. The enzyme had kinetic characteristics on T7 DNA identical to those of RNA polymerase purified by other more laborious procedures. |
