TelN Protelomerase, Recombinant

$ 70.00

TelN Protelomerase from E. coli bacteriophage N15 processes circular and linear plasmid DNA containing the target site telRL to produce linear double-stranded DNA with covalently closed ends. The 56-bp telRL target site consists of a central telO  palindrome of 22 bp and two 14-bp flanking sequences comprising inverted repeats. telO is separated from these repeats by 3 bp on each side. The telRL sequence is sufficient for TelN-mediated processing. TelN has cutting-ligating enzyme activity and covalently ligates at the cleavage site forming hairpin termini.

Source: A recombinant E. coli strain carrying bacteriophage N15 telN  gene.
Amino acids: 2-631 
Tag: His-tag
