Polymicrobial interactions stimulate resistance to host innate immunity through metabolite perception.

abstract：:Initiation of bovine papillomavirus (BPV) DNA synthesis in vivo and in vitro depends on the interaction of the viral initiator protein E1 with the replication origin (ori+ DNA). The viral E2 protein assists this interaction, resulting in a cooperative assembly of both proteins on the replication origin. Using gel mobi...
