- Isocaudomer
Isocaudomers are pairs of
restriction enzyme s that have slightly different recognition sequences but upon cleavage generate identical termini. For example the enzymes Mbo I and BamH I are isocaudomers:Mbo I N*GATCN NCTAG*N BamH I G*GATCC CCTAG*G
N represents any of the four
nucleotide s. Independently of which nucleotide is present when cleaving with MboI, after cleavage with either enzyme, all termini have the central tetranucleotide - GATC. This allows fragments generated with one enzyme to anneal with fragments generated with the other enzyme.
