One drawback to the use of peptides as therapeutics has been their susceptibility to proteolysis. Here, we have used an in vitro display technology, CIS display, to enhance the proteolytic resistance of ligand-binding peptides by selection of protecting motifs from a large peptide library. The premise to this selection was that certain linear peptides(More)
The Cox protein from bacteriophage P2 is a small multifunctional DNA-binding protein. It is involved in site-specific recombination leading to P2 prophage excision and functions as a transcriptional repressor of the P2 Pc promoter. Furthermore, it transcriptionally activates the unrelated, defective prophage P4 that depends on phage P2 late gene products(More)
The Cox protein from bacteriophage P2 forms oligomeric filaments and it has been proposed that DNA can be wound up around these filaments, similar to how histones condense DNA. We here use fluorescence microscopy to study single DNA-Cox complexes in nanofluidic channels and compare how the Cox homologs from phages P2 and WΦ affect DNA. By measuring the(More)
