论文摘要
<正>The Origin Recognition Complex （ORC） consists of six highly conserved subunits, Orc1-6.Despite the conservation in protein sequence, ORC from different species have divergent DNA binding specificities ranging from an absolute requirement for a specific sequence in Saccharomyces cerevisiae to no known sequence requirement in human. Yet, ORC from all species bind DNA to mark the sites for DNA replication initiation. Here, we have determined the cryo-EM structure of S. cerevisiae ORC bound to a 72-bp origin DNA containing the ARS consensus sequence （ACS） and B1 element at an overall resolution of 3.0?. In this structure,
