ATAD2 AAA+ ATPases are a family of histone chaperones that regulate nucleosome density and chromatin dynamics. Here, authors find that the fission yeast ATAD2 homolog Abo1 deposits histone H3–H4 onto DNA in an ATP-hydrolysis-dependent manner, and present the cryo-EM structure of an ATAD2 family ATPase to reveal the structural basis of nucleosome assembly by Abo1.
