Abstract

Tus is a protein involved in DNA replication termination that binds specific DNA sequences (Ter) located around the terminus region of the chromosome in Enterobacterales. Tus and Ter form a unique monomeric protein-DNA complex which is one of strongest of its kind. A fascinating aspect of Tus-Ter is its ability to dramatically change conformation into a locked structure upon progression of a replication fork towards the non-permissive face of the complex. Over the last two decades, several new technologies have emerged harnessing the unique and interesting properties of this fascinating DNA-binding protein. This review highlights the important properties of the Tus-Ter complex and their exploitation for the development of diverse and novel ultrasensitive detection devices as well as innovative genomic and proteomic platform technologies. A variety of ex vivo and in vivo bioanalytical applications are discussed, including immuno-PCR diagnostic, bioassay and protein array technologies that are broadly relevant to the fields of cancer biology, microbiology and immunology. A perspective on future research and applications is provided.
