We describe and characterize a complex reaction that catalyzes DNA supercoiling and chromatin assembly in vitro. A Xenopus oocyte extract supplemented with ATP and Mg++ converts DNA circles into minichromosomes that display a native, 200 bp periodicity. When supercoiled DNA is added to this extract it undergoes a time-dependent series of topological changes… CONTINUE READING
