Phage N15 telomere resolution. Target requirements for recognition and processing by the protelomerase.

Abstract excerpt

The Escherichia coli prophage N15 exists as a linear DNA molecule with covalently closed ends. Purified N15 protelomerase TelN is the only protein required to convert circular DNA substrates to the linear form with hairpin termini. Within the center of the telomerase occupancy site tos, the target for TelN is the 56-bp telRL consisting of the central 22-bp palindrome telO and two 14-bp flanking inverted sequence...
