Unusually wide co-factor tolerance in a metalloenzyme; divalent metal ions modulate endo–exonuclease activity in T5 exonuclease

T5 5′–3′ exonuclease is a member of a homologous group of 5′ nucleases which require divalent metal co-factors. Structural and biochemical studies suggest that single-stranded DNA substrates thread through a helical arch or hole in the protein, thus bringing the phosphodiester backbone into close pr...
