Purification and characterization of human topoisomerase I mutants.

Abstract

A system for rapid purification and characterization of eukaryotic topoisomerase-I mutants has been developed. The system utilizes six-histidine tagging of human topoisomerase I expressed in Saccharomyces cerevisiae to enable purification by nickel-affinity chromatography. Virtually homogenous mutant proteins are then tested for their ability to relax… (More)
