Crystal structures of λ exonuclease in complex with DNA suggest an electrostatic ratchet mechanism for processivity
The λ exonuclease is an ATP-independent enzyme that binds to dsDNA ends and processively digests the 5′-ended strand to form 5′ mononucleotides and a long 3′ overhang. The crystal structure of λ exonuclease revealed a toroidal homotrimer with a central funnel-shaped channel for tracking along the DN...
