Imaging the fate of histone Cse4 reveals de novo replacement in S
... Despite this simplicity, the architecture of Cse4 nucleosomes has become the subject of much debate. Cse4 nucleosomes have been reported to differ from the canonical nucleosome not only by the replacement of both molecules of histone H3 by the Cse4 variant, but also by the presence of chaperone Scm3 ...
