A fraction with the ability to bind the terminal fragment of equine adenovirus (EAd) DNA was prepared from MDBK cell nuclei. The fraction (MDBK nuclear factor) bound to the terminal fragment of all human and animal adenovirus DNAs examined except avian adenovirus EDS‐76. However, the terminal fragments of two animal adenoviruses, EAd and bovine adenovirus type 3 (BAd3), showed higher affinity for the nuclear factor than the others. The MDBK nuclear factor‐binding site determined by footprinting analysis was the sequence located between nucleotides 22 and 46 in EAd, between 36 and 53 in canine adenovirus type 2, and between 20 and 46 in BAd3, counting from the terminus. The respective binding site contained a sequence resembling the consensus sequence. The binding site of Ad4 DNA was not within the inverted terminal repetition, but was located at least 550 base pairs apart from the terminus.
