Cleavage activity of Tma endo V on 5′-labeled single-stranded and short I-containing substrates. (A) Exonuclease activity of Tma endo V mutants on 5′-labeled single stranded I-containing substrate. Cleavage reactions were performed as described in ‘Materials and Methods’ section with 100 nM enzyme and 10 nM substrate. (B) Exonuclease activity of Tma endo V mutants on 5′-labeled short I-containing substrate. Cleavage reactions were performed as described in ‘Materials and Methods’ section with 100 nM enzyme and 10 nM substrate.
